Question

点击广告并返回到应用程序后，键盘不会显示，但在此之前可以正常使用。同样，如果应用程序有多个屏幕，并且带有多个文本字段，它们也将无法正常工作。按下文本字段时，使键盘再次出现的唯一方法是强制关闭应用程序并再次启动。我尝试了一切，找不到解决方法。反正有什么解决办法或任何解决方法？

这是一个示例：

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

void main() {
  runApp(MyApp());
}

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Flutter Demo',
      theme: ThemeData(
        primarySwatch: Colors.blue,
      ),
      home: MyHomePage(title: 'Flutter Demo Home Page'),
    );
  }
}

class MyHomePage extends StatefulWidget {
  MyHomePage({Key key, this.title}) : super(key: key);

  final String title;

  @override
  _MyHomePageState createState() => _MyHomePageState();
}

class _MyHomePageState extends State<MyHomePage> {
  @override
  Widget build(BuildContext context) {
    myBanner
      ..load()
      ..show(
        anchorType: AnchorType.bottom,
      );
    return Scaffold(
      appBar: AppBar(
        title: Text(widget.title),
      ),
      body: Center(
        child: Card(
          child: TextField(),
          margin: EdgeInsets.all(50),
        ),
      ),
    );
  }
}

MobileAdTargetingInfo targetingInfo = MobileAdTargetingInfo(
  keywords: <String>['flutterio', 'beautiful apps'],
  contentUrl: 'https://flutter.io',
  childDirected: false,
);

BannerAd myBanner = BannerAd(
  adUnitId: BannerAd.testAdUnitId,
  size: AdSize.smartBanner,
  targetingInfo: targetingInfo,
  listener: (MobileAdEvent event) {
    print("BannerAd event is $event");
  },
);

不要忘记将firebase_admob添加到您的pubspec.yaml。

firebase_admob: ^0.7.0

编辑：同样在AndroidManifest.xml中添加这些行

 <meta-data
            android:name="com.google.android.gms.ads.APPLICATION_ID"
            android:value="ca-app-pub-3940256099942544~6300978111"/>

它应该看起来像这样

<!-- The INTERNET permission is required for development. Specifically,
     flutter needs it to communicate with the running application
     to allow setting breakpoints, to provide hot reload, etc.
-->
<uses-permission android:name="android.permission.INTERNET"/>

<!-- io.flutter.app.FlutterApplication is an android.app.Application that
     calls FlutterMain.startInitialization(this); in its onCreate method.
     In most cases you can leave this as-is, but you if you want to provide
     additional functionality it is fine to subclass or reimplement
     FlutterApplication and put your custom class here. -->

        <meta-data
