operator []= method

void operator []= (

1. int index,
2. Rectangle<num> value

)

override

Sets the value at the given index in the list to value.

The index must be a valid index of this list, which means that index must be non-negative and less than length.

Implementation

void operator []=(int index, Rectangle value) {
  throw new UnsupportedError("Cannot assign element of immutable List.");
}
