/// @assertion void insert(int index, E value)
/// Inserts the object at position [index] in the list.
/// This increases the length of the list by one and shifts all objects at or
/// after the [index] towards the end of the list.
/// An error occurs if the index is less than 0 or greater than length. An
/// UnsupportedError occurs if the list is fixed-length.
/// @description Checks that [UnsupportedError] is thrown since [Float32List] is
