FAILURE: Build failed with an exception, with a new Flutter project

[Yu Shen]

With a freshly installed Android Studio/Flutter SDK and a new Flutter project without changing the default code, all with the stable releases today Jan. 31, 2020, when I ran it, I got the following error message:

Launching lib\main.dart on Android SDK built for x86 in debug mode...

Running Gradle task 'assembleDebug'...

FAILURE: Build failed with an exception.

* What went wrong:

Could not determine the dependencies of task ':app:compileDebugJavaWithJavac'.

> Could not resolve all task dependencies for configuration ':app:debugCompileClasspath'.

   > Could not resolve io.flutter:flutter_embedding_debug:1.0.0-804dca62a17ca3bea4b508bc622218f88cfcd78f.

I tried two emulators, one with API 29, and one with API 27, both have the same error.

I have used the mirror site for Flutter (I'm not sure if it matters.)

Thanks in advance for your help!
