flutter_keyboard_visibility's Issues

jump nativepage mainveiw will release

jump to a native page, mainView will be released, plugin wont work anymore

MissingPluginException

Hey man,

Thank you for making this package, I am really excited to use it.
Unfortunately, the package throws a MissingPluginException:

`The following MissingPluginException was thrown while activating platform stream on channel github.com/adee42/flutter_keyboard_visibility:

MissingPluginException(No implementation found for method listen on channel github.com/adee42/flutter_keyboard_visibility)`

I cloned your repo, added it to my project and updated my dependencies. Any idea on why this is happening?

The plugin connectivity could not be built due to the issue above.

Normally when i connect my phone to the pc there is no problem with this library but when i try to get apk like "flutter build apk --release" it shows the error.

And it does not work in ios real device.

-------

Listener is not working when listener is disposed in dispose()

This code is not working. As soon as I remove the disposing of the listener, it works fine.

Btw: is there a way to get the event immediately? Not it's delayed when the keyboard is popping up.

final keyboardListener = KeyboardVisibilityNotification();

@override
void initState() {
  super.initState();
  keyboardListener.addNewListener(
      onChange: (bool visible) {
        print('KEYBOARD: $visible');
      },
    );
}

@override
void dispose() {
  keyboardListener.dispose();
  super.dispose();
}

Cant trigger listener in my own code

Hi,
Thanks for the plugin.

I can see that your example works. When I try to copy / paste the example code into my own code and include your library it doesn't seem to ever call the listener.
In the listener, I just put a print statement to show the $visible value but it never seems to be called.
Is there anything else I need to do to enable it ?

Fail to get mainView

@Override
    public void onActivityStarted(Activity activity) {
        try {
            mainView = ((ViewGroup)activity.findViewById(android.R.id.content)).getChildAt(0);
            mainView.getViewTreeObserver().addOnGlobalLayoutListener(this);
        }
        catch (Exception e) {
            // do nothing 
        }
    }

Change DidShow to WillShow

Hi, in your plugin you use DidShow, and WillHide

[center addObserver:self selector:@selector(didShow) name:UIKeyboardDidShowNotification object:nil];
[center addObserver:self selector:@selector(didHide) name:UIKeyboardWillHideNotification object:nil];

Could be possible to change UIKeyboardDidShowNotification with UIKeyboardWillShowNotification in order to make consistent with WillHide? Or maybe add it? Thanks!

Why this was broken????

0.5.3 ----> listening is broken
0.5.4,0.5.5 -----> java null pointer exception...

plz fix it

Only 0.5.2 works fine, what did you do??

Probably conflicts with another package

Thanks for making this! I am also using another package image_cropper: ^1.2.0
In my form page, I am using keyboard_visibility: ^0.5.7. It works fine. But when I open the image crop screen using the aforementioned package and come back to my form screen, keyboard_visibility package seems to stop working!
For now I am using a fork of this package flutter_keyboard_visibility: ^0.7.0 which seems to be working fine this scenario too.

Module 'flutter_keyboard_visibility' not found

When trying to build with Xcode I always get this issue.

Not working when back and navigate again to current screen

For example: It works normally in screen 2, but when back to previous screen and navigate again to screen 2, it can't detect if keyboard show or hide anymore. :<

where registrar.activity() return null because registration is happening in Application class, can you have a null check set for this.

Notification not working on some pages

@Rockvole @adee42 Did you ever make any progress on this? I'm having a similar problem - the listener seems to work in all of my app pages except one...and I have noooo idea why that could be.

application with flutter background view crash

just for information.

if i include your plugin inside a android application who use background flutter view (background service), application crash.

Application crash because a background service call "GeneratedPluginRegistrant.registerWith" with all plugin and your code haven't protection in this case (line 32 in KeyboardVisibilityPlugin)

LOG:

Ease integration of keyboard listener

Hey,

I have a lot of widgets implementing your listener, very useful. I developed a small mixing through which widgets can implement the listener by changing one line, it does the whole registering and disposing for you if you need just a basic listener. I thought I'd share the code, not sure if you want to add this as some kind of convenience but let me know if you want a PR :)

/// Adds keyboard listener functionality to your State
mixin KeyboardListenerMixin<T extends StatefulWidget> on State<T> {
  final _keyboardListener = KeyboardVisibilityNotification();
  int _keyboardVisibilitySubscriberId;
  bool isKeyboardVisible = false;
  
  @override
  @mustCallSuper
  void initState() {
    super.initState();
    _keyboardVisibilitySubscriberId = _keyboardListener.addNewListener(
      onChange: (bool visible) {
        setState(() {
          isKeyboardVisible = visible;
        });
      },
    );
    // init visibility state
    isKeyboardVisible = _keyboardListener.isKeyboardVisible;
  }

  @override
  @mustCallSuper
  void dispose() {
    _keyboardListener.removeListener(_keyboardVisibilitySubscriberId);
    _keyboardListener.dispose();
    super.dispose();
  }
}

Usage
Add the mixin to your widget state where you want the listener.

class YourStatefulWidgetState extends State<YourStatefulWidget> with KeyboardListenerMixin {

  @override
  Widget build(BuildContext context) {
    if (isKeyboardVisible) return ....something for visible keyboard....;
    return .....something for hidden keyboard....;
  }

}

0.5.6 is broken, back to 0.5.5 works fine

0.5.6 is broken, back to 0.5.5 works fine for me

My app is crashing because of this package

I was told to report this to you:

"Flutter's new background execution feature (described here: https://medium.com/flutter-io/executing-dart-in-the-background-with-flutter-plugins-and-geofencing-2b3e40a1a124) allows plugins to be registered in a background context (e.g. a Service)."

I don't know what this keyboard visibility package does and checked several packages I'm using and can't figure out who is calling it or why, but it's crashing my app, probably because of the warning above. Can you please update your package?

Unable to get viewInsets.bottom value correctly.

I noticed that the MediaQuery's "viewInsets.bottom" value is always "before" the keyboard show/hide is completed. Thus the value is always "0.00" when "shown" and "non-zero value" when "hidden".

Below is my code:

@override
  void initState() {
    KeyboardVisibilityNotification().addNewListener(
      onChange: (bool visible) {
        double keyboardHeight = getKeyBoardHeight();
        _newScreenHeight = _originalScreenHeight - (visible ? keyboardHeight : 0);
        setState(() {
          _screenHeight = _newScreenHeight;
        });
      },
    );
    super.initState();
  }

  double getKeyBoardHeight() {
    double keyboardHeight = MediaQuery.of(_loginContext).viewInsets.bottom;
    debugPrint("Bottom: "+keyboardHeight.toString());
    return keyboardHeight;
  }

Thank you very much for your effort and time. Appreciates.

Impossible to build apk on Flutter 1.12.13

Our projet has been migrated to AndroidX, but the same error appears when I build with the example of this plugin.

Do you know how to resolve this?

onChange event not fired

Hi. This plugin is not working for me.
What I did wrong?
My code is:

@override

  super.initState();

  KeyboardVisibilityNotification().addNewListener(
    onChange: (bool visible) {
      print(visible);
    },
  );

Package Needs Upgrade

When compiling my app which uses this package, the following error results:

FAILURE: Build failed with an exception.
* What went wrong:
Execution failed for task ':keyboard_visibility:verifyReleaseResources'.
> A failure occurred while executing com.android.build.gradle.internal.tasks.Workers$ActionFacade

This appears to me to indicate that this package needs to be upgraded to the latest Flutter version.

As you no-doubt know, it's simple to upgrade, just create a new package and copy the dart file over to it.

The application is broken

keyboard visibility breaks with integration of local_auth

Same issue flutter/flutter#55750,

Keyboard_visibility, https://pub.dev/packages/keyboard_visibility breaks, with the integration of local_auth, https://pub.dev/packages/local_auth breaks keyboard listeners.
Steps to reproduce:

Changing FlutterActivity in MainActivity.kt to FlutterFragmentActivity will cause all of the keyboard listeners to break (this is a necessary step in local_auth to be able to detect forms of biometric authentication)
Breaking code:

package com.example.testing

import androidx.annotation.NonNull;
import io.flutter.embedding.android.FlutterFragmentActivity
import io.flutter.embedding.engine.FlutterEngine
import io.flutter.plugins.GeneratedPluginRegistrant

class MainActivity: FlutterFragmentActivity() {
    override fun configureFlutterEngine(@NonNull flutterEngine: FlutterEngine) {
        GeneratedPluginRegistrant.registerWith(flutterEngine);
    }
}

Logs for local_auth:

How to destroy the listener, the listener is easy to superimpose

Calling setState inside onChange callback causes view reload and keyboard will not open

Has the title if I call setState like your example:

@override
void initState() {
  super.initState();

  _readCredentials();

  _keyboardVisible = _keyboardVisibility.isKeyboardVisible;

  _keyboardVisibilitySubscriberId = _keyboardVisibility.addNewListener(
    onChange: (bool visible) {
      setState(() {
        _keyboardVisible = visible;
      });
    },
  );
}

It cause the view reload and is keyboard immediatly closed.
I'm using the _keyboardVisible flat to show/hide a view.
How could I solve?

Request function to get Keyboard height

The old issue but seems doesn't work. [MissingPluginException]

(As my disappointed English, hoping you can understand my meanning)
Firts, thanks for your package!
It works well on the pure flutter project, but when I use it in a mixed app (add flutter to an existing Android app), it failed, and the message showing in the Run window when open the page:
"Another exception was thrown: MissingPluginException(No implementation found for method listen on channel github.com/adee42/flutter_keyboard_visibility)"
So, are you have any idea about this issue? or the existing solution is wonderful!
Look forward to your favourable reply.

Package does not exists - android

I am facing this issue today

can anyone help me to solve with this? I need to deploy the app to play store?

Update project to AndroidX

Is it possible to update the Android project to use the AndroidX libraries instead of the old support libraries like described here https://flutter.dev/docs/development/packages-and-plugins/androidx-compatibility#how-to-migrate-a-flutter-app-to-androidx ?

This would enable projects which are dependent on this one to migrate to AndroidX too (like ours 😊 )

Too much triggers

Is it possible to trigger only a single call when the keyboard is opened/closed? it triggers like 5 or 6 times every keyboard shown/hidden

can't listen to the keyboard collapse event by clicking the collapse keyboard button on the keyboard.

What should I get the keyboard height

Do we have to dispose of anything

Should we be disposing the listeners we are creating in the onDispose()?

Crashes application when application run in background

flutter_keyboard_visibility/android/src/main/java/com/github/adee42/keyboardvisibility/KeyboardVisibilityPlugin.java

Line 107 in 981f679

 registrar.activity().getApplication().registerActivityLifecycleCallbacks(instance); 

not work for the 1st time.

Hey, I'm new here. Today I simply git clone the code, and then run the example. No code has been changed.

It didn't work at the fist time, no matter how many times I toggled the keyboard.

But strangely, when I quited the app and entered it again, it worked!

Here's the flutter doctor msg:

Version 0.5.3 broking listeners for keyboard events (?)

Hi, i just update to 0.5.3 version and explore this bug.
In short words: in 0.5.2 it's works fine, but in 0.5.3 - listeners not working
detailed video with code example and emulator screen at https://youtu.be/Brh8pCvXcw4 (if quality is bad - wait several hours while youtube is upload a high quality of video)

A different SOLUTION for those who have problems with events

The events are not triggerred for me for X reasons, but I found a solution for my use case and since I'm not the only one here with this problem...

only for thoses who got TextField(s) in your business logic
You can check if the keyboard is visible or not by the NodeFocus.hasFocus property of your TextField
which have aswell a listener.

YourNodeFocus.addListener(() { print("Has focus: " + _nodeName.hasFocus.toString()); if (YourNodeName.hasFocus) { // keyboard visible } else { // keyboard hidden } });

Scotch solutions.
