remove method

bool remove (Object object)

Removes the first occurrence of value from this list.

Returns true if value was in the list, false otherwise.

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

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

// Note: 'head' has already been removed.
parts.remove('head'); // false
parts.join(', ');     // 'shoulders, knees, toes'

An UnsupportedError occurs if the list is fixed-length.

Implementation

bool remove(Object object) {
  throw new UnsupportedError("Cannot remove from immutable List.");
}
