下载

1. 下载depot_tools,并配置环境

git clone <https://chromium.googlesource.com/chromium/tools/depot_tools.git>

export PATH=/path/to/depot_tools:$PATH

2. Fork https://github.com/flutter/engine 到自己的账号下

3. 根目录创建.gclient文件

solutions = [
  {
    "managed": False,
    "name": "src/flutter",
    "url": "git@github.com:<your_name_here>/engine.git",
    "custom_deps": {},
    "deps_file": "DEPS",
    "safesync_url": "",
  },
]

4. 执行 gclient sync

5. 通过cd src/flutter进入flutter目录下,并执行git remote add upstream git@github.com:flutter/engine.git关联仓库

编译(Android)

1. 在src/flutter下执行git pull upstream master同步最新代码

2. gclient sync更新依赖

3. ./flutter/tools/gn --android --unoptimized --android-cpu=arm64 生成构建文件

4. ninja -C out/android_debug_unopt_arm64 编译

VSCode 配置

• C/CPP
编译完成之后,在out文件下会生成一个compile_commands.json,将这个文件添加到c_cpp_properties.json配置文件中

• Java
安装两个插件vscjava.vscode-java-pack和vscjava.vscode-java-dependency
配置JDK,但是目前要求版本最低为JDK11

问题以及解决办法

• C/CPP代码头文件总是报错,显示红色波浪线
