Flutter null safety migration build fails - 'FirebaseFirestoreWeb.runTransaction' has fewer named arguments than those of overridden method

We are trying to upgrade our flutter project to null safety migration using the following link https://dart.dev/null-safety/migration-guide.

After completion of above commands and trying to start app using flutter run

Failed to compile application.

We tried resolving the issue by upgrading flutter as below - (https://github.com/firebase/flutterfire/issues/9221)

flutter pub upgrade
Resolving dependencies...
Because project depends on cloud_firestore ^5.1.0 which doesn't match any versions, version solving failed.
pub finished with exit code 1
Solution

  • Try using cloud_firestore: ^4.4.5 which is latest stable on current data.

    cloud_firestore

    Then do

    • flutter clean
    • flutter pub get
    • check if there is any compile error
