我正在尝试测试一个应用程序.由于应用程序无法调试/运行,因此我一直在这个问题上遇到一个奇怪的问题. SDK版本为28,而其余的则为:

Flutter 1.13.9-pre.79 • channel master • https://github.com/flutter/flutter.git
Framework • revision 9eb9ea0ffa (6 hours ago) • 2020-01-13 21:30:42 -0800
Engine • revision 0235a50843
Tools • Dart 2.8.0 (build 2.8.0-dev.0.0 28c335d5a2)


Gradle Build无法生成.APK文件.这很可能 文件是在c:\ development \\ build下生成的,但是工具 找不到.

有没有办法通过此问题或可以通过提供或给出Gradle的输出路径来运行的配置? .APK似乎以错误状态生成.

Is there a way to pass this issue or a configuration that can allow me to run by providing or giving the output path to Gradle? The .apk seems to generated as the error states.

Android Studio -v 3.5.3 
Gradle -v 3.4.2 
Gradle Wrapper -v 5.1.1


in my case I have a multi flavor app like this:

update 04/15/2021:

    // Use IntelliSense to learn about possible attributes.

    "version": "0.2.0",
    "configurations": [
                    "name": "YOUR_PROJECT_NAME",
                    "program": "lib/main.dart",
                    "request": "launch",
                    "type": "dart",
                    "args": [
                            "ADD_YOUR_FLAVOR_NAME_HERE" //development or staging or production

Another way:

 android {


    buildTypes {
        release {
            // TODO: Add your own signing config for the release build.
            // Signing with the debug keys for now, so `flutter run --release` works.
            signingConfig signingConfigs.debug

    flavorDimensions "flavor-type"

            dimension "flavor-type"
            dimension "flavor-type"
            dimension "flavor-type"

So if you want to run app you have to write the flavor name and then the class name that hold main() function

flutter run --flavor staging -t lib/main_staging.dart

and I solved my error and built the .apk


Added the flavor name in Build name from Edit Configurations and it worked! enter image description here


Ok, I found that it's args in launch.json if you use vscode
