每当我尝试运行Flutter程序时，它都会卡在“正在运行Gradle任务'assembleDebug"中 [英] when ever I try to run my Flutter program, it gets stuck at “Running Gradle task 'assembleDebug”
问题描述
每当我尝试在仿真器或真实设备上运行时，它都会卡在"Running Gradle任务'assembleDebug" 上，并且整个计算机只会冻结并卡住，这是唯一的方法就是要重新启动它.
whenever I try to run in on an Emulator or on a real device, it get stuck at "Running Gradle task 'assembleDebug" and the entire computer just freezes and get stuck, and the only way out is to hard reboot it.
我正在使用华硕笔记本电脑(Windows 10)，内存为16GB.

推荐答案
发生这种情况的原因有很多:不接受android许可证，不兼容的sdk/flutter版本，Windows防火墙等.
There are lots of reasons why it's happening: Did not accept android-licenses, incompatible version of sdk/flutter, Windows Firewall etc.
如果您没有尝试过:
使用以下文件更新了文件android/app/build.gradle
Updated file android/app/build.gradle with
compileSdkVersion 29
运行:干净整洁
否则，请检查 Flutter应用卡在"Running Gradle任务" assembleDebug中'..."
或者如果您的 Android许可状态未知.
在没有sdkmanager的情况下安装Android Studio 取消选中隐藏过时的软件包"，您将看到Android SDK工具(过时)26.1.1.然后 flutter doctor --android-licenses
Android Studio installs without sdkmanager
Uncheck Hide Obsolete Packages and you'll see Android SDK Tools (Obsolete) 26.1.1.
and then flutter doctor --android-licenses
