颤动 - 卡在启动画面

Question

我尝试运行使用构建的移动应用程序，flutter但卡在启动屏幕上。使用adb logcat工具我可以看到一些错误/异常，但我不知道这些异常中的哪一个会导致错误：

Answer 1

该错误是通过调用平台渠道造成之前调用runApp。

从最后一个稳定的 Flutter 版本开始，这样做需要您WidgetsFlutterBinding.ensureInitialized();事先调用，以确保 Flutter 在您实际尝试使用平台通道与其进行通信之前绑定到它正在运行的平台。

在使用平台通道的任何其他代码之前调用它应该可以解决您的问题 - 我想您可以将它作为main()函数中的第一行代码：

WidgetsFlutterBinding.ensureInitialized();

编辑：我的回答仅对作者获得的特定内部异常有效：

E flutter : Tried calling: defaultBinaryMessenger
E flutter : #0      defaultBinaryMessenger (package:flutter/src/services/binary_messenger.dart:90)
E flutter : #1      MethodChannel.binaryMessenger (package:flutter/src/services/platform_channel.dart:140)
E flutter : #2      MethodChannel.invokeMethod (package:flutter/src/services/platform_channel.dart:314)

您可能会得到完全相同的外部异常，但内部异常（根本原因）完全不同，在这种情况下，我的回答不适用！
