How to start Flutter app as a background service on system startup-CodePudding

I'm wanting to automatically run my flutter application's background services as soon as the mobile is rebooted.

I implemented the following Solution, but it's throwing some errors

MainActivity.kt

package com.example.laravel_login
import android.os.Bundle
import android.provider.Settings
import io.flutter.embedding.android.FlutterActivity
import android.content.BroadcastReceiver
import android.content.Context;
import android.content.Intent;
class MainActivity: FlutterActivity() {
    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        var REQUEST_OVERLAY_PERMISSIONS = 100
        if (!Settings.canDrawOverlays(getApplicationContext())) {
            val myIntent = Intent(Settings.ACTION_MANAGE_OVERLAY_PERMISSION)
            val uri: Uri = Uri.fromParts("com.example.laravel_login.BootReceiver", getPackageName(), null)
            myIntent.setData(uri)
            startActivityForResult(myIntent, REQUEST_OVERLAY_PERMISSIONS)
            return
        }
    }
}

class BootReceiver: BroadcastReceiver() {
    override fun onReceive(context: Context, intent: Intent) {
        if (intent.action == Intent.ACTION_BOOT_COMPLETED) {
            val i = Intent(context, MainActivity::class.java)
            i.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK)
            context.startActivity(i)
        }
    }
}

AndroidManifest.xml

<!--       app auto restart on phone restart -->

            android:enabled="true"
            android:exported="true"

Add this to the imports of MainActivity.kt and you're good to go.

import android.net.Uri
