内容需包含：
1、BUG 描述
V/AudioManager( 6577): querySoundEffectsEnabled...
W/InputMethodManager( 6577): startInputReason = 3
W/HwRemoteInputMethodManager( 6577): isCasting false because IHwDistributedWindowManager is invalid.
I/InputMethodManager( 6577): showSoftInput
I/InputMethodManager( 6577): showSoftInput
I/AssistStructure( 6577): Flattened final assist data: 492 bytes, containing 1 windows, 3 views
E/flutter ( 6577): [ERROR:flutter/lib/ui/ui_dart_state.cc(209)] Unhandled Exception: BrnBottomPickerWidgetState#01adf(tickers: tracking 1 ticker) was disposed with an active Ticker.
E/flutter ( 6577): BrnBottomPickerWidgetState created a Ticker via its TickerProviderStateMixin, but at the time dispose() was called on the mixin, that Ticker was still active. All Tickers must be disposed before calling super.dispose().
E/flutter ( 6577): Tickers used by AnimationControllers should be disposed by calling dispose() on the AnimationController itself. Otherwise, the ticker will leak.
E/flutter ( 6577): The offending ticker was:
E/flutter ( 6577): _WidgetTicker(created by BrnBottomPickerWidgetState#01adf)
E/flutter ( 6577): The stack trace when the _WidgetTicker was actually created was:

2、复现步骤 BrnBottomWritePicker.show( context, title: '这里是标题', hintText: '请输入', cancelDismiss: true, confirmDismiss: false, onConfirm: (context, string) { BrnToast.show(string ?? '', context); return; }, onCancel: (_) { Navigator.of(context).pop(); return; }, defaultText: "", );
点击空白处关闭弹窗异常

- 系统
- Bruno 版本 ^2.2.0
- Flutter Doctor 信息
5、附加信息
包括视频、图片等补充信息
@MeiChao 感谢反馈，我在本地使用 iOS 15.2 模拟器运行【复现步骤】中代码，没有复现这个问题. 可否提供下复现的操作步骤，机型，flutter SDK 等信息。: )
@violinday 你好 操作步骤:
BrnBottomWritePicker.show( context, title: '这里是标题', hintText: '请输入', cancelDismiss: true, confirmDismiss: false, onConfirm: (context, string) { BrnToast.show(string ?? '', context); return; }, onCancel: (_) { Navigator.of(context).pop(); return; }, defaultText: "", );
点击BrnBottomWritePicker.show弹窗 关闭点阴影空白处异常

@zhoujuanjuan 修改建议：
[ERROR:flutter/lib/ui/ui_dart_state.cc(209)] Unhandled Exception: BrnBottomPickerWidgetState#5fa81(tickers: tracking 1 ticker) was disposed with an active Ticker. E/flutter (10682): BrnBottomPickerWidgetState created a Ticker via its TickerProviderStateMixin, but at the time dispose() was called on the mixin, that Ticker was still active. All Tickers must be disposed before calling super.dispose().
Tickers used by AnimationControllers should be disposed by calling dispose() on the AnimationController itself. Otherwise, the ticker will leak.
brn_bottom_picker.dart dispose方法 _controller.dispose(); 要在super.dispose();之前调用
@override void dispose() { _controller.dispose(); super.dispose(); }
