📃Documentation #



  • Update document


  • Delete useless print


  • 修改初始化的方式,现在更为通用

  • 支持自定义Toast的动画和持续时间😉

  • showEnhancedWidget方法的closeFunc参数其含义已经发生了变化了,现在是等待closeFunc函数执行完毕才移除Toast

  • 添加showAnimationWidget方法,可以使用此方法来高度自定义一个有动画的Toast🤩

  • 移除reInit方法(2.0版本不再需要),以及PreferDirection.BelowPreferDirection.Upside这两个已经被废除的枚举

  • WrapWidget类型方法参数发生变化(破坏性的),但是如果你没有直接使用showEnhancedWidget方式的话,这个修改对1.x版本的代码其实是无影响的,如果有使用请看这里进行兼容1.x版本升级到2.x版本

  • showXxxNotification 添加dismissDirections参数:表示能进行滑动关闭的方向

  • showXxxText,showXxxLoading,showXxxNotification等方法添加了align参数:表示ToastContent区域在MainContent区域的对齐,可用于自定义Toast放置的位置

  • 修复了showAttachedWidget方法的一些bug

  • 支持flutter web(注意不能确保其稳定性)

  • 更新example的样式,并添加了更多demo

  • Modify the way of initialization, now more general

  • Support for custom Toast animation and animation duration😉

  • The meaning of the closeFunc parameter of the showEnhancedWidget method has changed. Now it is wait for the closeFunc function to complete before removing Toast.

  • Add the showAnimationWidget method, you can use this method to highly customize an animated Toast🤩

  • Remove the reInit method and the two deprecated enumerations PreferDirection.Below and PreferDirection.Upside

  • WrapWidget type method parameter changed (not compatible with 1.x version),see 1.x version upgrade 2.x version

  • showXxxNotification Add dismissDirections parameter

  • showXxxText, showXxxLoading, showXxxNotification method adds align parameter

  • Fixed some bugs in the showAttachedWidget method

  • Support flutter web (note that it cannot ensure its stability)

  • Updated the style of example and added more demos


  • Bug fix:

The targetContext of the showAttachedWidget method causes a positioning error when it is inside the ScrollView.



  • 主要对showAttachedWidget方法进行了增强,现在支持更多方向,定位更准确了。

  • PreferDirection.BelowPreferDirection.Upside被废弃了,可以改用表达更清晰的topCenter,和bottomCenter来代替,且效果完全一致。这两个枚举将会在下个大版本被删除!

  • showAttachedWidgetpreferDirection 只是期望的方向,实际的位置可能因为空间不足而遭到调整

  • 实际调整顺序可以拿topLeft来进行说明,如果上方空间不足则调整为bottomLeft,然后左边空间不足的话就再判断右边的空间是否充足,充足的话结果为bottomRight,不充足最终结果为bottomCenter

  • 对于preferDirection=xxxCenter的情况,其交叉轴的偏移将会忽略


  • 修复当pop所有Route再push Route会出现Bug
  • 加固了当项目使用MaterialApp.navigatorKey,能使用reInit重新初始化


  • 放宽init重复初始化检查的程度
  • 替换scheduleFrame方法为ensureVisualUpdate


  • Toast关闭后,清理向BotToastNavigatorObserver注册的函数
