🐛 [firebase_auth] App crashing when calling verifyPhoneNumber on android emulator after updating firebase_auth to 0.20.0 from 0.18.4

[mbilalakmal]

Bug report

Describe the bug
After updating my flutter application to use firebase_auth 0.20.0, the app is crashing on my Android emulator (API 29).
The app does not crash on startup, but just after the phone verification method is invoked.

The issue maybe related to firebase-android-sdk issue.

Expected behavior

A clear and concise description of what you expected to happen.

This does look related to the Firebase Android SDK. @mikehardy thoughts - have you seen this one before?

[mikehardy]

Indeed, it's an existing bug in current firebase-android-sdk where they are missing the androidx browser dependency required by the recaptcha android auth flow. Trigger that and you'll crash.

Seen in react-native-firebase here invertase/react-native-firebase#4744
Upstream issue as linked above

Workaround that you must use until resolved, add dependency on browser into app/build.gradle:

 implementation "androidx.browser:browser:1.2.0"

We could consider including it in the firebase_auth build.gradle so people don't have to worry about it, with a note about when it may be removed (link to issue) but versioning may be problematic so we haven't done so in react-native-firebase either. I'm not satisfied with including it or not including it. It is not documented as a currently required workaround either, which is unsatisfying - could use a docs PR minimum

Enable Android Device Verification API on Google Cloud here

This solves the issue

[lancechentw]

androidx.browser:browser is mandatory when testing Firebase phone authentication in a android emulator, since the underlying com.google.firebase.firebase-auth performs a check on basicIntegrity value returned by Safetynet Attestation API, which is false in emulator environment.

So doing the followings will make a real device works, but not a emulator device

• Enable Android Device Verification API
• Add the SHA-256 key to Firebase project
• Update google-services.json

Happening on real device too (https://stackoverflow.com/questions/65839861/app-crash-while-using-firebase-phone-auth-in-android/65840172#65840172) after adding "implementation 'androidx.browser:browser:1.3.0' " in app/build.gradle it works fine
