Flutter应用程序在安卓平台中对firebase电话号码进行身份验证时崩溃

Question

我已经在Flutter项目中实现了Firebase Phone身份验证。在我点击"；"登录"；，应用程序崩溃并失去连接。

以下是代码(从互联网上获取(：

main.dart

import 'package:flutter/material.dart';
import 'loginpage.dart';
void main() {
runApp(MyApp());
}
class MyApp extends StatelessWidget {
@override
Widget build(BuildContext context) {
return MaterialApp(
debugShowCheckedModeBanner: false,
home: LoginPage(),
);
}
}

登录页面.dart

import 'package:firebase_auth/firebase_auth.dart';
import 'package:flutter/material.dart';
import 'dart:async';
class LoginPage extends StatefulWidget {
@override
_LoginPageState createState() => _LoginPageState();
}
class _LoginPageState extends State<LoginPage> {
String phoneNo, smssent, verificationId;
Future<void> verifyPhone() async {
final PhoneCodeAutoRetrievalTimeout autoRetrieve = (String verID) {
this.verificationId = verID;
};
final PhoneCodeSent smsCodeSent = (String verId, [int forceCodeResent]) {
this.verificationId = verId;
smsCodeDialogue(context).then((value) {
print("Code Sent");
});
};
final PhoneVerificationCompleted verifiedSuccess = (AuthCredential auth) {};
final PhoneVerificationFailed verifyFailed = (AuthException e) {
print('${e.message}');
};
await FirebaseAuth.instance.verifyPhoneNumber(
phoneNumber: phoneNo,
timeout: const Duration(seconds: 5),
verificationCompleted: verifiedSuccess,
verificationFailed: verifyFailed,
codeSent: smsCodeSent,
codeAutoRetrievalTimeout: autoRetrieve,
);
}
Future<bool> smsCodeDialogue(BuildContext context) {
return showDialog(
context: context,
barrierDismissible: false,
builder: (BuildContext context) {
return new AlertDialog(
title: Text('Enter OTP'),
content: TextField(
onChanged: (value) {
this.smssent = value;
},
),
contentPadding: EdgeInsets.all(10.0),
actions: <Widget>[
FlatButton(
onPressed: () {
FirebaseAuth.instance.currentUser().then((user) {
if (user != null) {
Navigator.of(context).pop();
Navigator.push(
context,
MaterialPageRoute(builder: (context) => LoginPage()),
);
} else {
Navigator.of(context).pop();
signIn(smssent);
}
});
},
child: Text(
"done",
style: TextStyle(color: Colors.white),
),
),
],
);
});
}
Future<bool> signIn(String smsCode) async {
final AuthCredential credential = PhoneAuthProvider.getCredential(
verificationId: verificationId,
smsCode: smsCode,
);
await FirebaseAuth.instance.signInWithCredential(credential).then((user) {
Navigator.push(
context,
MaterialPageRoute(
builder: (context) => LoginPage(),
),
);
}).catchError((e) {
print(e);
});
}
@override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
title: Center(
child: Text('PhoneNumber Login'),
),
),
body: Column(
mainAxisAlignment: MainAxisAlignment.center,
children: <Widget>[
Padding(
padding: const EdgeInsets.all(16.0),
child: TextField(
decoration: InputDecoration(
hintText: "Enter your phone number",
),
onChanged: (value) {
this.phoneNo = value;
}),
),
SizedBox(
height: 10.0,
),
RaisedButton(
onPressed: verifyPhone,
child: Text(
"verify",
style: TextStyle(color: Colors.white),
),
elevation: 7.0,
color: Colors.blue,
)
],
),
);
}
}

这是错误

Lost connection to device.
Exited (sigterm)

我可以知道出了什么问题吗？有人愿意帮我解决这个问题。。。

Answer 1

我只需在app/build.gradle依赖项中添加以下行就解决了这个问题。

dependencies {
implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version"
implementation 'com.google.firebase:firebase-auth'
implementation "androidx.browser:browser:1.2.0"

}

Answer 2

当收到OTP时，我还面临着应用程序崩溃的问题，并立即导致应用程序崩溃，为此我在下面添加了对android/app/build.gradle 的依赖

dependencies {
implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version"
implementation platform('com.google.firebase:firebase-bom:32.0.0')
implementation 'com.google.firebase:firebase-analytics-ktx'
implementation "androidx.multidex:multidex:2.0.1"
implementation "com.android.support:appcompat-v7:28.0.0"   // this is important
}
