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)

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: "",
);

@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。: )

[MeiChao]

@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

项目中Bruno 版本:
environment:
sdk: ">=2.7.0 <3.0.0"

@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();
}
