user_location_plugin's Issues

Marker is not diplayed when controller is not passed

While reviewing a feature request #6 I found out that the marker is not displayed when the mapController is not passed or used. This was also partly discussed by @jesusrp98 in #3

Plugin keeps the location service on forever

Describe the bug
If you are using this plugin the location service will be always on even if the app is running in the background. When you are using Google Maps, the location example, ... you will notice all of them turn the location service off when it's not used. But due to

user_location_plugin/android/src/main/kotlin/com/example/user_location/UserLocationPlugin.kt

Line 48 in af89e2d

locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER,

here the location service is kept on ... always.

To Reproduce
Steps to reproduce the behavior:

Run the example app
You will see the little location icon in the status bar, i.e. the app is accessing the location service.
Move the app to the background. The location service will be kept on. You still see the location icon in the status bar.

Expected behavior

The location service is not kept on forever. Like the Google Maps app, the location example, etc. it's off once the app goes into the background.

AnimationControllers dispose exception

Describe the bug

I'm very new in Dart and Flutter so I hope what I will describe will be helpful.
First, here is the trace:

Exception has occurred.
FlutterError (_MapsPluginLayerState#ace76(tickers: tracking 3 tickers) was disposed with an active Ticker.
_MapsPluginLayerState created a Ticker via its TickerProviderStateMixin, but at the time dispose() was called on the mixin, that Ticker was still active. All Tickers must be disposed before calling super.dispose().
Tickers used by AnimationControllers should be disposed by calling dispose() on the AnimationController itself. Otherwise, the ticker will leak.
The offending ticker was:
  _WidgetTicker(created by _MapsPluginLayerState#ace76(tickers: tracking 0 tickers))
  The stack trace when the _WidgetTicker was actually created was:
  #0      new Ticker.<anonymous closure> (package:flutter/src/scheduler/ticker.dart:69:40)
  #1      new Ticker (package:flutter/src/scheduler/ticker.dart:71:6)

  #9      _MapsPluginLayerState.setState (package:user_location/src/user_location_layer.dart:67:13)
  #10     _MapsPluginLayerState._subscribeToLocationChanges.<anonymous closure> (package:user_location/src/user_location_layer.dart:129:9)
  (elided 25 frames from dart:async))

To Reproduce
Steps to reproduce the behavior:
Switching back and forth on different views before the map animation finishes cause the crash.

Direction is inverted

Hi, thanks for this great plugin :).

I have a problem at least on a Huawei p30 I don't know if is the phone or if it's the plugin but the direction is inverted on the map. A part of that the speed is not real cause the -2

user_location_plugin/lib/src/user_location_layer.dart

Line 133 in 7449334

angle: ((_direction ?? 0) *

If I modify this line by:

(((_direction * -1) ?? 0) * (math.pi / 180) * -1) + 180,

All is working as expected.

Is this a real issue or I have something wrong configured?

thanks ;)

Add 'onLocationUpdate' parameter

Inside the UserLocationOptions class, add a new onLocationUpdate, which would be called once user's location has changed.

This example here would print the location every time it changes.

UserLocationOptions(
  context: context,
  ...
  onLocationUpdate: (LatLng pos) => print(pos),
)

The method 'cancel' was called on null.

Upon initial launch, and failing to grant location permissions, when navigating back, a NoSuchMethodError is thrown as a result of trying to close a stream that does not yet exist.

I/flutter ( 8256): The following NoSuchMethodError was thrown while finalizing the widget tree:
I/flutter ( 8256): The method 'cancel' was called on null.
I/flutter ( 8256): Receiver: null
I/flutter ( 8256): Tried calling: cancel()

Check for location permission when FAB is clicked

Show heading of user location marker

Is your feature request related to a problem? Please describe.
The heading of the device is not shown on user location marker

Describe the solution you'd like
Show the heading in user location marker, something similar to google maps might be good place to start

Describe alternatives you've considered
A clear and concise description of any alternative solutions or features you've considered.

Additional context
I am using this library and implemented routing, So, it would be nice to know where the user is heading.
Making use of simple_flutter_compass might be a good place to start
or compass_in_android

Location service crashes the app

Describe the bug
When the location service is turned off, you get prompted with a rationale for requesting permission (Android only), the Google's location service. If you click "No Thanks" you will get prompted again the same alert until the application finally crashes. Clicking "Ok" works fine, and enables locations service.
You can see the issue in the example.

To Reproduce
Steps to reproduce the behavior:

Go to Settings -> Location
Toggle the Location off
Return to the app
See error

Expected behavior
Clicking on "No Thanks" doesn't prompt the alert again.

Memory leak _MapsPluginLayerState line46

E/flutter (20257): The preferred solution is to cancel the timer or stop listening to the animation in the dispose() callback. Another solution is to check the "mounted" property of this object before calling setState() to ensure the object is still in the tree.
E/flutter (20257): This error might indicate a memory leak if setState() is being called because another object is retaining a reference to this State object after it has been removed from the tree. To avoid memory leaks, consider breaking the reference to this object during dispose().

Add 'tolerance' parameter

This new parameter would establish the limit when user's location should change.

If the change is less than tolerance, location and/or map shouldn't change.

UserLocationOptions(
  context: context,
  ...
  tolerance: 0.00001,
)

Markers doesn't render properly

I'm trying to render a list of markers, generated by data inside a Provider model.

FlutterMap(
  mapController: mapController,
  options: MapOptions(
    zoom: 17,
    minZoom: 5,
    maxZoom: 19,
    plugins: [
      UserLocationPlugin(),
    ],
  ),
  layers: [
    TileLayerOptions(
      urlTemplate: model.mapUrl,
      backgroundColor: Theme.of(context).canvasColor,
    ),
    MarkerLayerOptions(
      markers: [
        for (Museum museum in model.items)
          MapPin(
            title: museum.name,
            subtitle: museum.city,
            id: museum.id,
            location: museum.location,
          )
      ],
    ),
    UserLocationOptions(
      context: context,
      mapController: mapController,
      markers: ???,
    ),
  ],
)

Also, should I add the same markers inside the UserLocationOptions object? Documentation doesn't tell it clearly, since it's using an empty list :/

The MapPin object derives from the Marker class, there were no problem rendering them before implementing this package into the project.

Update flutter_compass dependency

Could you please update flutter compass to the latest version?

════════ Exception caught by widgets library ═══════════════════════════════════════════════════════
The following assertion was thrown building InkWell(gestures: [tap], clipped to BoxShape.rectangle, dirty, state: _InkResponseState<InkResponse>#83f44):
No Material widget found.

InkWell widgets require a Material widget ancestor.
In material design, most widgets are conceptually "printed" on a sheet of material. In Flutter's material library, that material is represented by the Material widget. It is the Material widget that renders ink splashes, for instance. Because of this, many material library widgets require that there be a Material widget in the tree above them.

To introduce a Material widget, you can either directly include one, or use a widget that contains Material itself, such as a Card, Dialog, Drawer, or Scaffold.

The specific widget that could not find a Material ancestor was: InkWell

Provide a way to move camera to the current location of the user

After the pull request #6 the user will be able to move the map freely, and the mapController will not redirect the user to their current location automatically. So, if the updateMapLocationOnPositionChange is set to false we must provide a way for the user to navigate to their current location.

I purpose of adding a flag called showMoveToCurrentLocationFloatingActionButton [which by default is true] that will display a button, which will redirect the user to their current location. The user shall also be able to provide their own button widget via moveToCurrentLocationFloatingActionButton optional parameter.

Version conflicts with flutter_map

Because user_location >=0.1.0 depends on flutter_map ^0.8.2 and community_base depends on flutter_map ^0.9.0, user_location >=0.1.0 is forbidden.

So, because xxx depends on user_location ^0.1.3, version solving failed.
pub get failed (1; So, because community_base depends on user_location ^0.1.3, version solving failed.)

Please update version. Thanks so much. :)

NoSuchMethodError in flutter testing on dispose

When I use the location plugin in my app, all tests fail with an NoSuchMethodError / Null Pointer Error.

The following NoSuchMethodError was thrown while finalizing the widget tree:
The method 'cancel' was called on null.
Receiver: null
Tried calling: cancel()

When the exception was thrown, this was the stack:
#0      Object.noSuchMethod (dart:core-patch/object_patch.dart:53:5)
#1      _MapsPluginLayerState.dispose (package:user_location/src/user_location_layer.dart:55:42)
#2      StatefulElement.unmount (package:flutter/src/widgets/framework.dart:4435:12)
#3      _InactiveElements._unmount (package:flutter/src/widgets/framework.dart:1748:13)
[...]

Apparently the _onLocationChangedStreamSubscription listener is never initialized but waiting in the user_location_layer.dart::101 indefinitely for the location permission request.

When disposed in line user_location_layer.dart:55:42 the cancel operation is called, without checking if the subscription ever succeeded.

To Reproduce
Steps to reproduce the behavior:

Implement location plugin in flutter project widget with flutter_map
Write test that starts the widget
Run "flutter test"

Expected behavior
No error, even without location permissions response.

Environment:

OS: Ubuntu 18.04
user_location Version: 0.1.2
flutter_map Version: 0.8.2
Flutter Version: 1.12.13
Dart Version: 2.7.0

Additional context
The tests are not about testing the plugins functionality or integration. The error appears already from instantiating the widget, without further interaction with the plugin.

can't run in the iOS

can you test it in the iOS plugin?

Callback for loose location

My problem is to know when the gps signal is loosed and inform to the user
I would like to display a message to the user when his position can be updated because the gps signal is loosed. I'm trying with different workarounds but they are not working well

Possible solution
I would like a callback in UserLocationOptions to manage that.

Thanks a lot in advance

When the phone rotate, the current location marker does not rotated.

The direction state have no updated??

version conflict?

Hello,
I get some proj4dart related error if not using flutter_map: ^0.9.0.
But now it seems that user_location cannot use that version.

Because user_location ^0.0.7 depends on flutter_map ^0.8.0 and user_location <0.0.7 depends on flutter_map ^0.7.0+2, user_location <0.1.0 requires flutter_map ^0.7.0+2 or ^0.8.0.
And because user_location >=0.1.0 depends on flutter_map ^0.8.2, every version of user_location requires flutter_map ^0.7.0+2 or >=0.8.0 <0.9.0.
So, because loyda_suomi depends on both flutter_map ^0.9.0 and user_location any, version solving failed.

In pubspec.yaml:

flutter_map: ^0.9.0
proj4dart: any 
user_location: any

I did not proceed to change files gradle.properties and build.gradle (in intructions it is not clear which one of the build.gradle)

Provide callback function to FAB

#69

Add 'updateMapOnStart' parameter

This optional parameter would update map's center always the first time it runs.

This option doesn't have much sense if the updateMapLocationOnPositionChange parameter is set to true, because the map will be always updated. It makes more sense once that other parameters is set to false. The map would start with the user front and center, but it wouldn't update map's center every time it moves.

I suggest changing this line

FlutterCompass.events.listen((double direction);

so that subscription could be declared as

StreamSubscription<double> _compassStreamSubscription;

and canceled in dispose

Current location marker does not change until map is moved

When updateMapLocationOnPositionChange option is set to false, current location marker does not change to a new location (although it prints new location in console) until the map is moved.

Location change notification not working as expected

Describe the bug
When the app is initially opened, and location permission is not given, the app awaits for location permission access. Once the permission is granted and the location access is toggled, the location access updates are not given.

On the other hand, if the location permission is already granted and then the location access is toggled, this status is given by the app.
To Reproduce
Steps to reproduce the behavior:

Disable location permission
Open the application
Allow the location permission
Turn off the location access of device
See error: The app will not ask to turn on the location access of device.
Expected behavior
The app should remind user to turn on the location service, when it is turned off, no matter what.

Chaning updateMapLocationOnPositionChange value on runtime doesn't work

I'm changing the value of the property updateMapLocationOnPositionChange on runtime to false but when the location is update the map is moving to the current location.

The idea is deactivate the tracking when the user moves the map and activate again when the user clicks on the center fab button.

Any idea how to deal with it?

Thanks
Regards

Location service crashes the app

Describe the bug
When I open the app with the location service turned off, it gives me the prompt to ask if I want to enable the location service. If I click 'No Thanks' or 'OK', it reproduces the prompt again and if I choose again 'No Thanks' or 'OK', it crashes the app. This only happens when the app is opened with the location service turned off.

To Reproduce
Steps to reproduce the behavior:

Turn off location service
Open the app
Choose 'No Thanks' or 'OK'
See error

Expected behavior
Prompt disappears when 'No Thanks' is clicked or enables location service when 'OK' is clicked.

defaultZoom not utilised

Describe the bug
While UserLocationOptions accepts defaultZoom as an argument, the setting does not seem to be utilised at all.

For example, I would expect the following snippet to open a map at the user's location with zoom level 19:

UserLocationOptions(
      context: context,
      mapController: mapController,
      markers: markers,
      zoomToCurrentLocationOnLoad: true,
      updateMapLocationOnPositionChange: false,
      defaultZoom: 19
    );

However, the method handling zoomToCurrentLocationOnLoad hard-codes a zoom level of 17:

user_location_plugin/lib/src/user_location_layer.dart

Line 186 in d7e1cbe

_currentLocation, 17, widget.options.mapController, this);

Happy to submit a PR.

To Reproduce
Steps to reproduce the behavior:

Create a map using the settings above
Observe default zoom

Expected behavior
See above

Error after hide map screen

E/flutter (32734): [ERROR:flutter/lib/ui/ui_dart_state.cc(157)] Unhandled Exception: setState() called after dispose(): _MapsPluginLayerState#50975(lifecycle state: defunct, not mounted, tickers: tracking 0 tickers)
E/flutter (32734): This error happens if you call setState() on a State object for a widget that no longer appears in the widget tree (e.g., whose parent widget no longer includes the widget in its build). This error can occur when code calls setState() from a timer or an animation callback.
E/flutter (32734): The preferred solution is to cancel the timer or stop listening to the animation in the dispose() callback. Another solution is to check the "mounted" property of this object before calling setState() to ensure the object is still in the tree.
E/flutter (32734): This error might indicate a memory leak if setState() is being called because another object is retaining a reference to this State object after it has been removed from the tree. To avoid memory leaks, consider breaking the reference to this object during dispose().
