Protection screen

The problem we identified is the need for enhanced security in our app. Many users store sensitive information within the app, making it crucial to protect their data from unauthorized access. Our solution is to implement a protection screen that will act as a barrier to the app's content, requiring authentication before granting access.

Features

This plugin provides you 3 different methods to add protection to your app

• PIN
• Pattern
• Fingerprint

with high preferable customization

Demo

## How to Use 1- Go to `android/app/src/main/AndroidManifest.xml`

Add the following line to the AndroidManifest.xml file:

<uses-permission android:name="android.permission.USE_FINGERPRINT"/>

• this tag is used to declare permissions that your Android application requires to access certain features or resources on the device

2- Go to android/app/src/main/kotlin/MainActivity.kt

replace the MainActivity.kt file with :

package com.example."the name of your project "
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);
    }
}

• This setup allows you to create a hybrid app with both native Android components and Flutter UI seamlessly integrated.

• make you main async (start the main with tow line):

WidgetsFlutterBinding.ensureInitialized();
await initialize();

3- Go to android/app/bulid.gradle file add to the defaultConfig this tow lines

multiDexEnabled true
minSDK 21

• inside runApp call Protector and pass your Application entrie point us a child to the this class.

• to clear the saved authentication data call

clear()

4- the usage :

• pattern : to give the user the accessability to

choose pattern method (true by default) (bool)
