Quickstart

Run this command in your root project:

dart pub add -d reactter_lint custom_lint

And then include these lines of code into analysis_options.yaml:

analyzer:
  plugins:
    - custom_lint

Then you can see suggestions in your IDE or you can run checks manually:

dart run custom_lint

Lints

hook_late_convention

The hook late must be attached an instance.

Bad

Cause: ReactterHook cannot be late without attaching an instance.

class AppController {
  final otherState = UseState(0);
  late final stateLate = UseState(otherState.value);
  ...
}

Good

Fix: Use Reactter.lazy for attaching a instance.

class AppController {
  final otherState = UseState(0);
  late final stateLate = Reactter.lazy(
    () => UseState(otherState.value),
    this,
  );
  ...
}

hook_name_convention

The hook name should be prefixed with use.

Bad

Cause: The hook name is not prefixed with use.

class MyHook extends ReactterHook {
  ...
}

Good

Fix: Name hook using use preffix.

class UseMyHook extends ReactterHook {
  ...
}

invalid_hook_position

The hook must be defined after the hook register.

Bad

Cause: The hook cannot be defined before the hook register.

class UseMyHook extends ReactterHook {
  final stateHook = UseState(0);
  final $ = ReactterHook.$register;
  ...
}

Good

Fix: Define it after the hook register.

class UseMyHook extends ReactterHook {
  final $ = ReactterHook.$register;
  final stateHook = UseState(0);
  ...
}

invalid_hook_register

The hook register('$' field) must be final only.

Bad

Cause: The hook register cannot be defined using getter.

class MyHook extends ReactterHook {
  get $ => ReactterHook.$register;
  ...
}

Cause: The hook register cannot be defined using setter.

class UseMyHook extends ReactterHook {
  set $(_) => ReactterHook.$register;
  ...
}

Cause: The hook register cannot be defined using var keyword.

class UseMyHook extends ReactterHook {
  var $ = ReactterHook.$register;
  ...
}

Cause: The hook register cannot be defined using a type.

class UseMyHook extends ReactterHook {
  Object $ = ReactterHook.$register;
  ...
}

Good

Fix: Define it using final keyword.

class UseMyHook extends ReactterHook {
  final $ = ReactterHook.$register;
  ...
}
