100% Shared Code Android/iOS Login Example - JSON API

Flutter Login Example

This example uses a ScrollView, JSON Rest API, Navigation, Alert Pop Up, Progress Indicator, Globals, Images in a shared asset folder, and 100% Shared Code. Now with the ability to login with FaceID, TouchID, and Fingerprint Reader on Android.

Online Demo: https://rodydavis.github.io/flutter_login/

New Features

• Auto Login
• Enhanced Security with Bio
• Menu and Logout
• Dark Mode and True Black
• Settings Page
• Auth Service
• What's New Page
• Remember Me Toggle
• Custom Theme
• Scoped Model
• Automatic Json using json_serializable

Getting Started

Clone or Fork Project to get started.

Prerequisites

Flutter SDK, Android Studio or Other Compatible IDE.

iOS Integration

Note that this plugin works with both TouchID and FaceID. However, to use the latter, you need to also add:

<key>NSFaceIDUsageDescription</key>
<string>Why is my app authenticating using face id?</string>

to your Info.plist file. Failure to do so results in a dialog that tells the user your app has not been updated to use TouchID.

Android Integration

Update your project's AndroidManifest.xml file to include the USE_FINGERPRINT permissions:

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
          package="com.example.app">
  <uses-permission android:name="android.permission.USE_FINGERPRINT"/>
<manifest>

Sticky Auth

You can set the stickyAuth option on the plugin to true so that plugin does not return failure if the app is put to background by the system. This might happen if the user receives a phone call before they get a chance to authenticate. With stickyAuth set to false, this would result in plugin returning failure result to the Dart app. If set to true, the plugin will retry authenticating when the app resumes.

How to modify UI when using local auth plugin in flutter ?

Hello,

I wanted to check if there is a way to modify the UI that appears for the local authentications. Say for example, below is how the screen would look when the finger print auth appears in the flutter app.

Below is an example of how the same would look like in other native apps like Walnut, for example.

Is there a way to dig in to the native layer and easily modify the UI to at least make it a bit better ?

Hey,

first of all thx for this great Scaffold for a flutter app.

those last two lines repeat several more times.

Any Ideas?

From the UI perspective it seems that there isn't any issue at all.

let me know if I could further help tackling this...

Desktop

biometric plugin wont work on desktop.

is there a way to compile for desktop then ?

Or create two flutter apps and:

• then at runtime detect if you on mobile and then use it.
• Or do condition compilation strategy.

not sure what architectural strategy to employ. Maybe IOC ( inversion of control) pattern with something like dio ?

The plugins `get_version, local_auth` use a deprecated version of the Android embedding.

I guess this is because of the new flutter updates.
How do I fix it?

The pluginsget_version, local_auth` use a deprecated version of the Android embedding.
To avoid unexpected runtime failures, or future build failures, try to see if these plugins support the Android V2 embedding. Otherwise, consider removing them since a future release of Flutter will remove these deprecated APIs.
If you are plugin author, take a look at the docs for migrating the plugin to the V2 embedding: https://flutter.dev/go/android-plugin-migration.

Generated files under VCS

After building the project for Android on my system (Windows) there are some files modified in Git which I think shouldn''t be under VCs as they get modified for different contributors and/or builds.
I'm new to Flutter and have some experience with Android projects, so I'm not sure exactly what files might be safely skipped. These are the files and dirs I suspect:

android/.gradle
pubspec.lock
local.properties

also might be ios/Pods/Manifest.lock and *.lock files in general

best way to make this "my own"?

this might be useful in the Readme too

I will create a PR for this if needed once the informations are collected.

my current observations are, that search and replace "flutter_login" -> "your_project" works in a way.

I'm not sure though if it's everything that is needed because of two things:

1. if you git clone again flutter_login and build the app, it gets overwritten and it feels like it shares some data with the renamed project
2. if you create a flutter project from scratch and just copy lib and pubspec.yaml over, it print build errors for me from cocoapods which are rather cryptic...

thx in advance

Future<String> getData(Map params) / token questions

https://github.com/AppleEducate/flutter_login/blob/5a04073845988613cf7e576362966512bec2a6d2/lib/globals.dart#L82

1. can you show how you'd use the params that this method takes in?
2. when would its response ever contain 'Invalid Token' ? i noticed Future checkToken() calls it.
   https://github.com/AppleEducate/flutter_login/blob/5a04073845988613cf7e576362966512bec2a6d2/lib/signin/auth_service.dart#L97
3. i don't see the token getting checked. could you give a sample or point me to where it is?
4. how is the mapData expected to be used? i couldn't see what the expected usage from the assignment alone: https://github.com/AppleEducate/flutter_login/blob/5a04073845988613cf7e576362966512bec2a6d2/lib/signin/auth_service.dart#L26
5. how is the code below this comment involved in getting a token? https://github.com/AppleEducate/flutter_login/blob/5a04073845988613cf7e576362966512bec2a6d2/lib/signin/auth_service.dart#L24
   from looking at the uuid package, i guess the only part of this code that's involved in getting a token is:
   var uuid = new Uuid();
   String ..., _token;
   _token = uuid.v4().toString();
   is that right?
6. when would validToken ever be false? it seems there's nothing that would prevent uuid from creating the token, as it's doing? https://github.com/AppleEducate/flutter_login/blob/5a04073845988613cf7e576362966512bec2a6d2/lib/signin/auth_service.dart#L55

thank you!

Server side

This is really awesome security package.
Could you publish the server side code it expects ?

My intention is to integrate this with golang server and use grpc for networking.
Would be happy to publish it.
