Question

在 VS Code 上启动 flutter 应用程序时出现错误

我在网上尝试了很多解决方案，但都没有成功，我也尝试重新安装Windows，但也没有成功

Answer 1

对我有用的

解决方案：Ubuntu 20.04、adb 33.0.1、Android Studio Bumblebee 2021.1.1：

1. Android Studio > 设置 > 构建、执行、部署 > 调试器： 设置“使用现有手动管理服务器”端口 5038。

2. 关闭Android Studio
3. android-sdk/platform-tools/adb Kill-server 的路径
4. android-sdk/platform-tools/adb 启动服务器的路径
5. 启动Android Studio

事件日志显示无法到达 ADB 服务器，这很好。当您使用第 3 点和第 4 点中的命令运行时，adb 将在端口 5037 上启动。如果 Studio 连接到手动启动的 adb，它会杀死它。这就是为什么必须在 Studio 设置中设置 5038（而不是 5037）。

下次重新启动后，您只需执行 4. 和 5.

Answer 2

我已通过以下步骤解决了此错误：

1. 转到 {C://Users/{Name}/.gradle} - 删除 .gradle 文件。

2. 然后在其他位置下载并安装相同的flutter和dart SDK版本并设置环境变量。

Example:

Environment variables Before  : ("D:\FlutterExtractedFiles\flutter\bin") ("D:\FlutterExtractedFiles\flutter\bin\cache\dart-sdk\bin")

Environment variables After : ("C:\edgedownloads\flutter_windows_v1.12.13+hotfix.8-stable\flutter\bin") ("C:\edgedownloads\flutter_windows_v1.12.13+hotfix.8-stable\flutter\bin\cache\dart-sdk\bin")

3. 然后请检查 android studio 事件日志

Answer 3

我在 vs code 中也有类似的问题。唯一对我有用的解决方案是从 .vscode/settings.json

 中删除所有“

--no-sound-null-safety

”设置

{
    "xd.globalEditor": false,
    "xd.lastPackage": "/Users/username/Downloads/material-theme 2",
    "java.configuration.updateBuildConfiguration": "automatic",
    // "dart.flutterTestAdditionalArgs": ["--no-sound-null-safety"],
    // "dart.flutterAdditionalArgs": ["--no-sound-null-safety"],
    // "dart.vmAdditionalArgs": ["--no-sound-null-safety"],
}

Answer 4

通过从 android studio 重新连接 SDK 路径到项目，我在 pop os 求解器上遇到了同样的问题。
