注意:我正在使用具有稳定 channel 版本的 CodeMagic.io 进行构建。
任何想法？
最佳答案
该错误是由调用平台 channel 引起的之前 调用runApp .
自上一个稳定的 Flutter 版本以来，这样做需要您调用 WidgetsFlutterBinding.ensureInitialized();事先，确保在您实际尝试使用平台 channel 与其进行通信之前，Flutter 已绑定(bind)到其运行的平台。
在使用平台 channel 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() 中的第一行代码。功能:
WidgetsFlutterBinding.ensureInitialized();
