问题demo

FlutterSmartDialog.init(
          loadingBuilder: (String msg) => CustomSmartLoadingWidget(msg),
          toastBuilder: (msg) => CustomSmartToastWidget(msg),
        )

class _CustomSmartLoadingWidgetState extends State<CustomSmartLoadingWidget> {
  @override
  Widget build(BuildContext context) {
    return Center(
      child: Column(
        mainAxisSize: MainAxisSize.min,
        children: [
          Lottie.asset(AppLottie.loading, width: 50, fit: BoxFit.fitWidth, animate: true, repeat: true),
          if (widget.msg.isNotEmpty == true)
            const SizedBox(
              height: 30,
            ),
          if (widget.msg.isNotEmpty == true)
            Text(
              widget.msg,
              style: TextStyles.tsPrimary14,
            ),
          if (widget.btnText?.isNotEmpty == true)
            Container(
                width: double.infinity,
                margin: const EdgeInsets.only(left: 90, right: 90, top: 30),
                child: MaterialButton(
                  elevation: 0,
                  height: 48,
                  shape: RoundedRectangleBorder(borderRadius: BorderRadius.circular(24)),
                  color: AppColor.primary,
                  onPressed: widget.btnOnTap,
                  child: Text(
                    widget.btnText ?? '',
                    style: const TextStyle(fontSize: 16, fontWeight: FontWeight.bold),
                  ),
                ))
        ],
      ),
    );
  }
}

这demo写的是个啥？重新弄下吧，能直接运行的全部简化代码

[SeeYouWilsen]

看错了 不是这个引起的 是因为在有loading的时候 又弹了一个新的loading 导致前面设置的不起效果了

[SeeYouWilsen]

但是好像这种弹起多个loading情况也没有办法避免,有办法让他永远只弹同一个吗?比如单例?

[xdd666t]

loading本来就是单个overlayEntry，后一个会顶掉前一个，这个只是你对loading设置不一样导致的

[SeeYouWilsen]

就是后面的顶掉前面的 会导致loading的效果看上去会有闪动 有办法让它始终保持这一个loading吗?

[xdd666t]

我周末想想怎么弄

[SeeYouWilsen]

感谢! 辛苦了!

• 解决了，试下新版本吧

dependencies:
  flutter_smart_dialog: ^4.9.3+1

• 测试代码

void _showLoading() async {
  SmartDialog.showLoading(msg: "test one");
  await Future.delayed(const Duration(seconds: 1));
  SmartDialog.showLoading(msg: "test two");
  await Future.delayed(const Duration(seconds: 1));
  SmartDialog.showLoading(msg: "test three");
  await Future.delayed(const Duration(seconds: 1));
  SmartDialog.dismiss();
}

太棒了！非常感谢！
