isItemSelectedByScope<T> method

bool isItemSelectedByScope<T>(
  1. T item
)

便捷判断项目是否选中（使用 Scope 中定义的 getItemId）

Implementation

bool isItemSelectedByScope<T>(T item) {
  final inherited =
      dependOnInheritedWidgetOfExactType<ListSelectInherited<T>>();
  if (inherited == null) return false;
  return inherited.state.isItemSelectedByItem(item, inherited.getItemId);
}
