null safety & fklutter_web_auth

[chrislaurie-io]

I'm trying to run use OAuth2 in my app with null safety (sdk: ">=2.12.0 <3.0.0")

But when I build the app I get the following compile error:

Error: Cannot run with sound null safety, because the following dependencies don't support null safety:

• package:flutter_web_auth 2

For solutions, see https://dart.dev/go/unsound-null-safety 2

FAILURE: Build failed with an exception.

using: oauth2_client: ^2.0.0-nullsafety

make sure you are using flutter_web_auth a null safety version
