android - Flutter:Gradle 构建无法生成 .apk 文件。该文件可能是在 \build 下生成的，但该工具找不到它

Question

我正在尝试测试应用程序。由于应用程序无法调试/运行，我一直遇到一个奇怪的问题。 SDK 版本为 28，其余版本如下:

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 failed to produce an .apk file. It's likely that this file was generated under C:\Development\\build, but the tool couldn't find it.

有没有办法通过提供或提供输出路径给 Gradle 来传递此问题或允许我运行的配置？ .apk 似乎是作为错误状态生成的。



更新:

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

就我而言，我有一个这样的多口味应用程序:
2021 年 4 月 15 日更新:

{
    // Use IntelliSense to learn about possible attributes.
    // Hover to view descriptions of existing attributes.
    // For more information, visit: https://go.microsoft.com/fwlink/?linkid=830387
    "version": "0.2.0",
    "configurations": [
            {
                    "name": "YOUR_PROJECT_NAME",
                    "program": "lib/main.dart",
                    "request": "launch",
                    "type": "dart",
                    "args": [
                            "--flavor",
                            "ADD_YOUR_FLAVOR_NAME_HERE" //development or staging or production
                        ]
            }
    ]

另一种方式:

 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"

    productFlavors{
        development{
            dimension "flavor-type"
        }
        staging{
            dimension "flavor-type"
        }
        production{
            dimension "flavor-type"
        }
    }
}

因此，如果您想运行应用程序，则必须编写 flavor 名称，然后编写包含 main() 函数的类名称

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

我解决了我的错误并构建了.apk
