Flutter Firebase Email 无密码登录 - 链接错误

Question

I have a flutter app in which I'm trying to use firebase Email passwordless sign in. The sending part is working, but when I open the link I get an error:

The handleCodeInApp parameter in the actioncode settings is true however.

_firebaseAuth.sendSignInLinkToEmail(
  email: email.value,
  actionCodeSettings: firebase_auth.ActionCodeSettings(
    url: uri.toString(),
    iOSBundleId: "myPackageName",
    androidPackageName: "myPackageName",
    androidMinimumVersion: '0',
    androidInstallApp: false,
    handleCodeInApp: true,
    dynamicLinkDomain: "myPackageName",
  ),
);

The Uri gets created here:

DynamicLinkParameters parameters = DynamicLinkParameters(
  uriPrefix: 'https://myRegisteredDomain',
  link: Uri.parse('https://myRegisteredDomain'),
  androidParameters: AndroidParameters(
    packageName: 'myPackageName',
    minimumVersion: 0,
  ),
  iosParameters: IosParameters(
    bundleId: 'myPackageName',
    minimumVersion: '0',
  ),
);
return await parameters.buildUrl();

Intent filter is set up as follows:

<intent-filter>
    <action android:name="android.intent.action.VIEW"/>
    <category android:name="android.intent.category.DEFAULT"/>
    <category android:name="android.intent.category.BROWSABLE"/>
    <data android:host="myRegisteredDomain" android:scheme="https"/>
    <data android:host="myRegisteredDomain" android:scheme="http"/>
</intent-filter>

In firebase I have set up the domain as needed and it has been whitelisted. At this point I have no idea why I'm even getting this error as handleCodeInApp is set to true. I can only guess that my link is incorrect in some way, but I wouldn't know where I set it up wrong. If anyone knows where I went wrong or you need additional information, please tell me.

Solution

1. The Uri generated using the DynamicLinkParameters does not work. Just use a string like: "https://PROJECT.page.link". This solved the error I was getting.

2. The isSignInWithEmailLink check from FirebaseAuth isn't working correctly with version ^0.20.0+1, which I was using. Reference https://github.com/FirebaseExtended/flutterfire/issues/4711#issuecomment-762323661 on how to fix this. After this fix I can now use Passwordless sign in as intended

You should follow Firebase Email Link Authentication example guide at FlutterFire
