use-existing-destructuring

v1.26.0
warning
dart 3.0+
pro+

Warns when there is an existing class or record destructuring that can be used instead of accessing the property directly.

Example​

❌ Bad:

void fn(SomeClass variable) {
  // LINT: One of the patterns above uses the same initializer.
  //  Try updating that destructuring and use it here instead.
  final SomeClass(:value) = variable;

  print(variable.another);
}

void fn() {
  final (left, _) = _getRecord();
  
  // LINT: One of the patterns above uses the same initializer.
  //  Try updating that destructuring and use it here instead.
  print(_getRecord().$2);
}

✅ Good:

void fn(SomeClass variable) {
  final SomeClass(:value, :another) = variable;

  print(another);
}

void fn() {
  final (left, right) = _getRecord();
  
  print(right);
}
