Flutter Device Preview and Firebase Auth Incompatible

Question

Pubspec.yaml
dependencies:
flutter: sdk: flutter bloc: ^6.1.0 cloud_firestore: ^0.14.3 cupertino_icons: ^1.0.0 device_preview: ^0.5.5 firebase_auth: ^0.18.3 firebase_core: ^0.5.2 firebase_storage: ^5.0.1 fl_chart: ^0.12.2 flutter_bloc: ^6.1.1 flutter_sms: ^2.1.1 flutter_spinkit: ^4.1.2+1 flutter_svg: ^0.19.1 google_nav_bar: ^3.1.0 http: ^0.12.2 liquid_swipe: ^1.5.0 location: ^3.2.1 page_transition: ^1.1.7+3 persistent_bottom_nav_bar: ^3.1.0 regexpattern: ^1.0.0

ERROR RECEIVED

Because firebase_auth >=0.18.3 <=0.18.3 depends on firebase_auth_web ^0.3.2 and no versions of firebase_auth match >0.18.3+1 <0.18.4, firebase_auth >=0.18.3 <0.18.3+1 or >0.18.3+1 <0.18.4-∞ requires firebase_auth_web ^0.3.2.
Because firebase_auth >=0.18.4 <=0.18.4 depends on firebase_auth_web ^0.3.2+2 and firebase_auth >=0.18.4+1 depends on firebase_auth_web ^0.3.2+3, firebase_auth >=0.18.4 requires firebase_auth_web ^0.3.2+2. Thus, firebase_auth >=0.18.3 <0.18.3+1 or >0.18.3+1 requires firebase_auth_web ^0.3.2.
And because firebase_auth 0.18.3+1 depends on firebase_auth_web ^0.3.2+1, firebase_auth >=0.18.3 requires firebase_auth_web ^0.3.2.
And because firebase_auth_web >=0.3.0-dev.1 depends on intl ^0.16.1 and every version of flutter_localizations from sdk depends on intl 0.17.0-nullsafety.2, firebase_auth >=0.18.3 is incompatible with flutter_localizations from sdk.
And because device_preview 0.5.5 depends on flutter_localizations any from sdk and no versions of device_preview match >0.5.5 <0.6.0, firebase_auth >=0.18.3 is incompatible with device_preview ^0.5.5.

There are some dependency version issues, let me know how to correct it.

Solution

To solve the issue, you can take the following steps to check for the compatible version

1. Change the version number of the flutter_bloc to any
2. This will resolve the issue
3. You can then check which version was automatically selected and use it

remove the version and use the key word any let me know if it solves. For instance, firebase_auth: any

I see the same firebase mess. Did you manage to solve it?

Using any solved my problem. Thank you @Hamza
