operator []= method Null safety

void operator []=(
  1. Object object,
  2. T? value

Sets this Expando's property value on the given object to value.

Properties can effectively be removed again by setting their value to null.

The object must not be a number, a string, a boolean, a record, null, a dart:ffi pointer, a dart:ffi struct, or a dart:ffi union.
