Question

我已经安装了Windows 10 64位，Android Studio和Visual Studio Code。我已经安装了Flutter SDK。这是“ flutter doctor -v”的结果：

PS C:\Users\mafer> flutter doctor
Doctor summary (to see all details, run flutter doctor -v):
[√] Flutter (Channel beta, 1.19.0-4.3.pre, on Microsoft Windows [versÃ£o 10.0.19041.330], locale pt-BR)

[√] Android toolchain - develop for Android devices (Android SDK version 30.0.1)
[√] Android Studio (version 4.0)
[√] VS Code (version 1.47.0)
[√] Connected device (2 available)

• No issues found!

但是当我要在Visual Studio或Android Studio中创建应用程序时，会收到以下消息，并且项目文件夹和文件未正确创建。

Flutter crash report.
Please report a bug at https://github.com/flutter/flutter/issues.
## command
flutter --no-color create --template app --description F2it application. --org com.f2it runners_app
## exception
TemplateException: Value was missing for variable tag: androidFlutterJar. (4:24)
<root url="jar://{{{androidFlutterJar}}}!/" />

出了什么问题？
