Flutter Local (Inbuilt) Authentication usage

Hi folks,

Today I will explain the process of using local (in-built) authentication usage in Flutter.

Pre-requisites

1. pubspeck.yaml update

dependencies:
local_auth: ^0.6.2+3

2. Install the packages from command line

$ flutter pub get

Note: In Visual Studio Code or Android Studio automatically by saving the pubspec.yaml file packages will get updated

Usage

1. Import the package in the respective dart file (say main.dart)

import 'package:local_auth/local_auth.dart';

Troubleshooting

1. I/flutter : PlatformException(no_fragment_activity, local_auth plugin requires activity to be a FragmentActivity., null)

Open /android/app/src/main/kotlin/../MainActivity.kt
Update the file with following content

package com.[your.package]

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);
}
}
