remove method

bool remove (
  1. Object? element
)
override

Removes the first occurrence of value from this list.

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

var 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'

The list must be growable.

Implementation

bool remove(Object? element) {
  for (int i = 0; i < this.length; i++) {
    if (this[i] == element) {
      this._closeGap(i, i + 1);
      return true;
    }
  }
  return false;
}
