Overview

Ignore defined_value_getter_type lint if return Future type.

Copilot Summary

Details

This pull request primarily addresses two files in the nilts and nilts_test packages, introducing support for asynchronous functions in the DefinedValueGetterType lint rule and updating the MainButton class to align with these changes. The most significant changes are the addition of a check for Future return types in the lint rule and the introduction of Future return type functions in the MainButton class.

Lint Rule Changes:

• packages/nilts/lib/src/lints/defined_value_getter_type.dart: Updated the DefinedValueGetterType lint rule to include a check for Dart's Future return type. This change allows the lint rule to correctly handle asynchronous functions.

MainButton Class Changes:

• packages/nilts_test/test/lints/defined_value_getter_type.dart: Added Future<int> Function() as a possible type for onReturnPressed, onFutureReturnPressed, onNullableReturnPressed, and onNullableFutureReturnPressed in the MainButton class. This change ensures that the class can handle asynchronous functions that return an int. [1] [2] [3]
