flutter 小白，请问如何在 Windows 上编译？

[Sciroccogti]

尝试编译了一下，有很多关于类似 main.mapper.g.dart 的报错，似乎是需要提前进行编译？

项目中使用了dart_json_mapper这个需要build_runner的支持(已经在项目中引用)，最简单的就是在项目编写中开启下面的命令

pub run build_runner watch

或者每次启动前，先执行下

pub run build_runner build

明白了，感谢！

不过目前还有 依赖项不支持 Nullsafety，故尚未能在 flutter >= 1.24 下编译成功。

@Sciroccogti 版本更新那么快呀，我是跟着稳定版走的。现在才1.22.5

害，我这默认下载似乎就是 1.26，好像是因为要启用 Desktop 版，得用 Dev 分支。

@Sciroccogti 我这里用的不是官方的桌面版噢，我这里用的是go-flutter

啊对哦。。。怪不得

[Sciroccogti]

pub run build_runner build

根据 https://github.com/flutter/flutter/issues/19049#issuecomment-402287617 ，命令似乎已经更改为 flutter packages pub run build_runner build lib

[Sciroccogti]

已经能够在 Ubuntu 20.04 上编译，这里记录一下环境和方法。

• Flutter：git 仓库的 beta 分支
• dart：apt 安装
• hover

运行

flutter packages pub run build_runner build lib
hover build linux

文件生成在 ./go/build/outputs/linux-release/

这里附上我编译的 clash_for_flutter-0331-linux.zip

[mapleafgo]

其实

flutter pub run build_runner build

依然可以的，但在这之前尽量先运行

flutter pub get

同步更新你的依赖
