全屏通知颤动

Question

我正在使用Flutter开发出租车预订应用程序。当用户预订出租车时，卖方会收到有关预订的通知，然后由他决定是否要确认预订。我想要的是供应商获得全屏通知。我该如何在颤抖中实现这一目标。我目前正在使用fcm通知。请帮我！预先感谢。

为了使事情变得简单，只需使用此plugin

示例代码：

import 'package:flutter/material.dart';
import 'dart:async';

import 'package:flutter/services.dart';
import 'package:flutter_android_pip/flutter_android_pip.dart';

void main() => runApp(new MyApp());

class MyApp extends StatefulWidget {
  @override
  _MyAppState createState() => new _MyAppState();
}

class _MyAppState extends State<MyApp> {
  String _platformVersion = 'Unknown';

  @override
  void initState() {
    super.initState();
    //  initPlatformState();
  }
/*
  // Platform messages are asynchronous, so we initialize in an async method.
  Future<void> initPlatformState() async {
    String platformVersion;
    // Platform messages may fail, so we use a try/catch PlatformException.
    try {
      platformVersion = await FlutterAndroidPip.platformVersion;
    } on PlatformException {
      platformVersion = 'Failed to get platform version.';
    }

    // If the widget was removed from the tree while the asynchronous platform
    // message was in flight, we want to discard the reply rather than calling
    // setState to update our non-existent appearance.
    if (!mounted) return;

    setState(() {
      _platformVersion = platformVersion;
    });
  }*/

  @override
  Widget build(BuildContext context) {
    return new MaterialApp(
      home: new Scaffold(
        appBar: new AppBar(
          title: const Text('Plugin example app'),
        ),
        body: new Center(
          child: new RaisedButton(
            child: new Text("press"),
            onPressed: () {
              FlutterAndroidPip.enterPictureInPictureMode;
            },
          ),
        ),
      ),
    );
  }
}

全屏是什么意思？您可以为驱动程序应用程序的新通知设置侦听器，然后可以启动新活动，在此活动中可以构建全屏布局并显示所需的数据。
