问题描述

在我用颤振开发的项目中，我收到以下错误。我突然收到了这个错误。通常我的项目正在运行，我没有改变任何东西，我开始收到这个错误。

我在下面列出了我的文件的错误输出和图像。我在哪里做错了或为什么会出现此错误，您能帮忙吗？

解决方案

Maven 存储库未添加到您的 build.gradle 文件中。它应该看起来像这样

allprojects {
    repositories {
        google()
        mavenCentral()
    }
}

如果您的 Android 文件夹有其他问题，您只需删除/androidFlutter 项目中的文件夹并通过运行再次生成 Android 构建flutter create --platform=android [PROJECT_PATH]
