如何在 Android 上添加 FLAG_SECURE 10 - Flutter

Question

I have a Flutter project and I need to add a FLAG_SECURE on Android.

Currently, this is the code on my main activity:

import android.os.Bundle
import io.flutter.app.FlutterActivity
import io.flutter.plugins.GeneratedPluginRegistrant
import android.view.WindowManager.LayoutParams;

class MainActivity: FlutterActivity() {
  override fun onCreate(savedInstanceState: Bundle?) {
    super.onCreate(savedInstanceState)
    GeneratedPluginRegistrant.registerWith(this)
  }

  public override fun onPause() {
      super.onPause()
      getWindow().addFlags(LayoutParams.FLAG_SECURE)
  }

  public override fun onResume() {
    super.onResume()
    getWindow().clearFlags(LayoutParams.FLAG_SECURE)
  }
}

This is working fine except with Android 10.

Examples:

Android 9:

Android 10:

You can easily achieve same with flutter plugin flutter_windowmanager

add Plugin

dependencies:
   flutter_windowmanager: ^0.2.0

import package in main file

import 'package:flutter_windowmanager/flutter_windowmanager.dart';

Add this line based on your need

 await FlutterWindowManager.addFlags(FlutterWindowManager.FLAG_SECURE);

Its done...
