fix(flutter): widen plus plugin constraints

[ChiragAgg5k]

Summary

• allow package_info_plus 10.x and device_info_plus 13.x in generated Flutter SDKs
• align the declared Dart and Flutter minimums with the existing device_info_plus 11.5.0 requirement
• retain compatibility with older supported toolchains through Pub's SDK-aware version resolution

Tests

• php example.php flutter client
• flutter pub get (Flutter 3.35.6; resolved compatible package_info_plus 9.0.1 and device_info_plus 12.4.0)
• flutter test
• composer lint-twig
• composer refactor:check

Greptile Summary

The PR widens the Flutter SDK’s allowed device_info_plus and package_info_plus versions while raising and documenting the corresponding Dart and Flutter minimums.

• Allows device_info_plus 13.x and package_info_plus 10.x during Pub resolution.
• Declares Dart 3.7 and Flutter 3.29 as generated Flutter SDK minimums.
• Updates the repository compatibility table to match the generated package metadata.

Confidence Score: 5/5

The PR appears safe to merge.

No blocking failure remains; the compatibility table now matches the Dart and Flutter minimums declared by generated Flutter packages.
