Flutter调试Linux平台代码（VSCode）

Flutter 开发过程中，需要编写调试 Linux 平台相关的代码，下面介绍一下使用 VSCode 进行调试的相关配置。

在工程根目录下的 launch.json 中增加如下配置：

        {
            "name": "Debug native",
            "type": "cppdbg",
            "request": "launch",
            "program": "${workspaceFolder}/build/linux/arm64/debug/bundle/MyApp", // Path to your compiled Flutter Linux executable
            "args": [],
            "stopAtEntry": false,
            "cwd": "${workspaceFolder}",
            "environment": [],
            "externalConsole": false,
            "MIMode": "gdb",
            "setupCommands": [
                {
                    "description": "Enable pretty-printing for gdb",
                    "text": "-enable-pretty-printing",
                    "ignoreFailures": true
                }
            ]
        },

{

"name": "Debug native",

"type": "cppdbg",

"request": "launch",

"program": "${workspaceFolder}/build/linux/arm64/debug/bundle/MyApp", // Path to your compiled Flutter Linux executable

"args": [],

"stopAtEntry": false,

"cwd": "${workspaceFolder}",

"environment": [],

"externalConsole": false,

"MIMode": "gdb",

"setupCommands": [

{

"description": "Enable pretty-printing for gdb",

"text": "-enable-pretty-printing",

"ignoreFailures": true

}

]

注意 "program": "${workspaceFolder}/build/linux/arm64/debug/bundle/MyApp", // Path to your compiled Flutter Linux executable 根据项目的实际情况进行配置。

完整的配置如下：

{
    // 使用 IntelliSense 了解相关属性。 
    // 悬停以查看现有属性的描述。
    // 欲了解更多信息，请访问: https://go.microsoft.com/fwlink/?linkid=830387
    "version": "0.2.0",
    "configurations": [
        {
            "name": "Debug native",
            "type": "cppdbg",
            "request": "launch",
            "program": "${workspaceFolder}/build/linux/arm64/debug/bundle/MyApp", // Path to your compiled Flutter Linux executable
            "args": [],
            "stopAtEntry": false,
            "cwd": "${workspaceFolder}",
            "environment": [],
            "externalConsole": false,
            "MIMode": "gdb",
            "setupCommands": [
                {
                    "description": "Enable pretty-printing for gdb",
                    "text": "-enable-pretty-printing",
                    "ignoreFailures": true
                }
            ]
        },
    ]
}

{

// 使用 IntelliSense 了解相关属性。

// 悬停以查看现有属性的描述。

// 欲了解更多信息，请访问: https://go.microsoft.com/fwlink/?linkid=830387

"version": "0.2.0",

"configurations": [

{

"name": "Debug native",

"type": "cppdbg",

"request": "launch",

"program": "${workspaceFolder}/build/linux/arm64/debug/bundle/MyApp", // Path to your compiled Flutter Linux executable

"args": [],

"stopAtEntry": false,

"cwd": "${workspaceFolder}",

"environment": [],

"externalConsole": false,

"MIMode": "gdb",

"setupCommands": [

{

"description": "Enable pretty-printing for gdb",

"text": "-enable-pretty-printing",

"ignoreFailures": true

}

]

}

调试的时候，参考下图进行选择，选择的配置项目就是 "name": "Debug native",如下图：

西门子洗碗机SN23E831TI排水泵故障维修

最近家里的西门子洗碗机不工作了，故障表现就是洗碗不结束，面板上的进水龙头指示灯闪烁，永远不结束。仔细观察，触摸洗碗机，会发现洗碗机外部凉凉的，不加热。洗碗中途打开柜门，里面没有温度。只要没有温度，大概率故障原因就是加热模块损坏。

访问github.com被解析到127.0.0.1问题解决

最近访问 github，发现总是访问失败。经过排查后确认问题原因是 DNS 解析被污染导致 github.com 被解析到 127.0.0.1 导致的。

如下图：

解决方案：

1、指定DNS为其他知名DNS服务器：如1.1.1.1，8.8.8.8， 114.114.114.114等；

2、添加hosts文件记录，将github的ip地址增加进去。

H3CBook Pro 14 G2合盖睡眠导致指纹解锁不可用M2硬盘丢失问题

公司新发的 H3CBook Pro 14 G2 使用了 Intel i7 1360P 当前 BIOS 版本号 F.11 版本日期 12/27/2024 。机器自带内存 16GB，感觉不大够用。到手之后，买了一个新的 32GB DDR5 内存，顺手插上了老电脑上替换下来的一个 Intel M2 固态硬盘。默认情况下合盖会进入自动睡眠状态。重新打开盖子，指纹解锁不可用，进入系统之后，新增的 M2 硬盘丢失。重启系统后可以恢复。

跟客服也沟通了一下，目前暂时没有新的 BIOS 版本发布。目前的解决方案就是在 Windows 11 的电源设置里面关闭合盖 “睡眠” 选项，全部设置为 “休眠”。
