AnchorBuilder typedef

AnchorBuilder = Widget Function(BuildContext context, GlobalKey<State<StatefulWidget>> scrollKey, ScrollController scrollController, bool reverse, Axis scrollDirection, List<GlobalKey<State<StatefulWidget>>> entryKeys)

Implementation

typedef AnchorBuilder = Widget Function(
    BuildContext context,

    /// 务必把 [scrollKey] 赋值给 滚动组件[key]
    GlobalKey scrollKey,

    /// 务必把 [scrollController] 回传给 builder 里的滚动组件
    ScrollController scrollController,

    /// 如果使用 [reverse] 务必把 [reverse] 回传给 builder 里的滚动组件 默认为 false
    bool reverse,

    /// 如果使用 [scrollDirection] 务必把 [scrollDirection] 回传给 builder 里的滚动组件 默认为 Axis.vertical
    Axis scrollDirection,

    /// 务必将 entryKeys[index] 赋值给 子元素[key]
    List<GlobalKey> entryKeys);
