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