我正在尝试学习Flutter.我的问题是，当我第一次运行flutter项目时，它会在设备上成功运行并成功安装，但是如果我断开设备并重新运行项目，则会出现错误.

I am trying to learn Flutter. My problem is that when I run my flutter project for the first time it runs and installs successfully on the device, but if I disconnect the device and rerun the project it gives an error.

我正在尝试在我的应用中显示图像.

I am trying to display images in my app.

当我运行 flutter clean 或 flutter clean build 或 flutter clean cache 并重新运行项目时，它没有给出错误，然后断开设备连接，问题再次出现.我在Google上搜索了几个小时，但没有帮助我.这是错误:

When I run flutter clean or flutter clean build or flutter clean cache and rerun the project it does not gives the error, then after disconnecting the device the problem occurs again. I searched google for hours but it did not help me. this the the error:

推荐答案

我从文件的当前位置删除了该文件，并进行了运行，以使flutter再次重新构建该文件，并且该文件可以正常工作.

I deleted the file from its current location and made a run to make flutter re-build the file again and it worked.
