When I ran my flutter project, it gave me this error

The current Dart SDK version is 2.17.0-105.0.dev.

Because lints 2.0.0 requires SDK version >=2.17.0-206.0.dev <3.0.0 and no versions of lints match >2.0.0 <3.0.0, lints ^2.0.0 is forbidden.

So, because firebase_flutter depends on flutter_lints ^2.0.0 which depends on lints ^2.0.0, version solving failed.

pub get failed (1; So, because firebase_flutter depends on flutter_lints ^2.0.0 which depends on lints ^2.0.0, version solving failed.)

Is there anybody who can help me please?

There is 'pub outdated' command.

You can analyze 'flutter pub outdated' or 'dart pub outdated' command.
And you can update all 'flutter pub upgrade' or 'dart pub upgrade'.

You are probably using beta, dev or master Flutter channel instead of stable.

Simply run flutter upgrade to get the latest Flutter version, which should include a newer Dart beta version as well.

Remove the version Code in front of package its automatically adapt competible version.
