Analysis suggestions

Package not compatible with SDK dart

because of import path [vehicle_keyboard] that is in a package requiring null.

Health suggestions

Fix lib/vehicle_keyboard.dart. (-0.50 points)

Analysis of lib/vehicle_keyboard.dart reported 1 hint:

line 7 col 7: This class (or a class that this class inherits from) is marked as '@immutable', but one or more of its instance fields aren't final: VehicleKeyboard.controller

Maintenance issues and suggestions

The description contains too many non-ASCII characters. (-20 points)

The site uses English as its primary language. The value of the description field in your package's pubspec.yaml field should primarily contain characters used in English.

Support latest dependencies. (-10 points)

The version constraint in pubspec.yaml does not support the latest published versions for 1 dependency (flutter_screenutil).

The package description is too short. (-20 points)

Add more detail to the description field of pubspec.yaml. Use 60 to 180 characters to describe the package, what it does, and its target use case.

Package is pre-v0.1 release. (-10 points)

While nothing is inherently wrong with versions of 0.0.*, it might mean that the author is still experimenting with the general direction of the API.

Maintain an example.

None of the files in the package's example/ directory matches known example patterns.

Common filename patterns include main.dart, example.dart, and vehicle_keyboard.dart. Packages with multiple examples should provide example/
