我有一个正在管理音频通话的应用程序。调用添加项并且应用程序在后台运行时,我需要将应用程序置于前台状态。我尝试使用Navigator.push,但没有任何结果。

您可以使用软件包bringtoforeground。就其版本而言,它还处于早期阶段,但是可以正常工作。
iOS
但这仅适用于android ,您必须记住,背景上的iOS应用已被破坏。你可以读这个吗 see details here
Android
因此,此实现仅适用于Android。
此程序包的最好之处在于,您可以将它与Firebase Cloud Messaging(FCM)或其他任何程序一起使用。
这是他们的示例,Bringtoforeground.bringAppToForeground();
这是您用于将应用程序置于前台的代码。
import 'dart:async';
import 'package:bringtoforeground/bringtoforeground.dart';
import 'package:flutter/material.dart';
import 'package:flutter/services.dart';
void main() => runApp(MyApp());
class MyApp extends StatefulWidget {
@override
_MyAppState createState() => _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 {
Timer.periodic(Duration(seconds: 10), (t) {
Bringtoforeground.bringAppToForeground(); //This is the only thing that matters
});
} 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 MaterialApp(
home: Scaffold(
appBar: AppBar(
title: const Text('Plugin example app'),
),
body: Center(
child: Text('Running on: $_platformVersion\n'),
),
),
);
}
}
