@FullChargeComplete
请问你是在调用closeAllLoading报的错吗？

[FullChargeComplete]

是的 �我调用了 BotToast.closeAllLoading();

[FullChargeComplete]

可能是toast 已经被close 掉了才报这个错

[MMMzq]

@FullChargeComplete
这种情况是稳定复习的还是概率性的?

[MMMzq]

closeAllLoading我在项目及基本没有用,所以该方法的测试可能没有其他方法那么完全.

[FullChargeComplete]

应该是我的问题 我每次请求会自动 toast 一下 完成都会closeAll ，有没有检查 是否还有toast 存在的方法？

[MMMzq]

1. closeAllLoading正常来说,多次调用是OK的,出现现在这种情况说明 closeAllLoading还是有点问题的
2. 没有检查的功能

不知道能不能提供一个能复现的demo?

[FullChargeComplete]

import 'package:bot_toast/bot_toast.dart';

bool loading = false;
Set dict = Set();

void beforeRequest(uri, Map<dynamic, dynamic> options) {
  dict.add(uri);
  if (loading == false) {
    showAppLoading(options);
    loading = true;
  }
}

void afterResponse(uri, Map<dynamic, dynamic> options) {
  dict.remove(uri);
  if (dict.length == 0 && loading == true) {
     BotToast.closeAllLoading();
    loading = false;
  }
}

/*
 * loading: 可配置参数
 * requestOrComplete: 是否发送请求或已完成 true表示发送请求需要开启loading，false表示完成请求可关闭loading
 */
void showAppLoading(Map<dynamic, dynamic> options) {
  options = {
    'text': options['text'] ?? 'loading...'
  };
   BotToast.showLoading();
  
}

[FullChargeComplete]

这个是我的代码

[MMMzq]

@FullChargeComplete
看起来很正常,你现在是每次都能重现吗?

[FullChargeComplete]

对的 经常出现
还有 在BotToast.showText 回调 pop 会报错
BotToast.showText(text: '提现申请提交成功,等待后台审核',onClose: (){
Navigator.pop(context);
});

报这个
flutter: Another exception was thrown: setState() or markNeedsBuild() called when widget tree was locked.
我没有在回调里面setstate

[MMMzq]

@FullChargeComplete
Navigator.pop(context); 会间接调用相关方法.注意的是onClose的触发时机是Toast的dispose函数,所以说你可能需要使用 SchedulerBinding.instance.addPostFrameCallback包裹.像下面这样

  SchedulerBinding.instance.addPostFrameCallback((_) {
    Navigator.pop(context);
  });

[MMMzq]

你能尝试把:
bot_toast_manager.dart
这一行改成下面那样,看看有没有问题？

_map.clear();

[FullChargeComplete]

嗯嗯 谢谢大佬 我试试

[MMMzq]

@FullChargeComplete
你好，我这边修改了一下,你这边方便使用下dev分支来测试一下有没有问题吗?
使用方式:

dependency_overrides:
  bot_toast:
    git:
      url: https://github.com/MMMzq/bot_toast.git
      ref: dev

[MMMzq]

这个错误本质上应该是和 #43 是一样的
