listen method

void listen(
  1. _Listen<T>? listen, {
  2. bool change = true,
})
  • 监听变化 change = false, 不变化也会监听notify，不会触发builder
  • Listen for change = false, it listens for notify without changing, builder will not be triggered

Implementation

void listen(_Listen<T>? listen, {bool change = true}) {
  _change = change;
  _listen = listen;
}
