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.
