remove method

bool? remove(
  1. Object? valueToRemove
)

Removes the first occurrence of value from this list.

Returns true if value was in the list, false otherwise. The list must be growable.

final parts = <String>['head', 'shoulders', 'knees', 'toes'];
final retVal = parts.remove('head'); // true
print(parts); // [shoulders, knees, toes]

The method has no effect if value was not in the list.

final parts = <String>['shoulders', 'knees', 'toes'];
// Note: 'head' has already been removed.
final retVal = parts.remove('head'); // false
print(parts); // [shoulders, knees, toes]

Implementation

bool? remove(Object? valueToRemove) {
  if (value == null) return null;
  late bool _result;
  update((_) => _result = value!.remove(valueToRemove));
  return _result;
}
