remove method

  1. @override
bool remove(
  1. Object? value
)
override

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

@override
bool remove(Object? value) {
  final int index = _list.indexOf(value as T);
  if (index == -1) {
    return false;
  }
  _list.removeAt(index);
  notifyListeners(ListChangeDetails<T>(const [], [value], index));
  return true;
}
