dart_mappable_builder incompatible with SDK 3.5.0

[lhengl]

Upgrading the environment to the latest Flutter/SDK version causes the build_runner to produce the following warning:

Analyzer language version: 3.4.0
SDK language version: 3.5.0

Please update to the latest analyzer version (7.0.0) by running
flutter packages upgrade.

If you are not getting the latest version by running the above command, you
can try adding a constraint like the following to your pubspec to start
diagnosing why you can't get the latest version:

dev_dependencies:
analyzer: ^7.0.0

Upgrading the analyzer to ^7.0.0 will cause the following error:

Because dart_mappable_builder 4.3.0 depends on analyzer >=5.11.0 <7.0.0 and no versions of dart_mappable_builder match >4.3.0 <5.0.0, dart_mappable_builder ^4.3.0 requires analyzer >=5.11.0 <7.0.0.

Perhaps the build_mappable_builder pubspec should be changed to:

analyzer: '>=5.11.0 <8.0.0'
