Question

当我尝试在Flutter中合并移动和Web代码库时，看到以下错误：

webdev could not run for this project.
This version of webdev does not support the `build_daemon` protocol used by your version of `build_runner`.
Please add a dev dependency on `build_daemon` with constraint: >=1.0.0 <2.0.0
pub finished with exit code 78

我的pubspec.yaml如下：

environment:
  sdk: '>=2.2.0 <3.0.0'

dependencies:
  flutter_web: any
  flutter_web_ui: any

dev_dependencies:
  # Enables the `pub run build_runner` command
  build_runner: ^1.1.2
  # Includes the JavaScript compilers
  build_web_compilers: ^1.0.0

# flutter_web packages are not published to pub.dartlang.org
# These overrides tell the package tools to get them from GitHub
dependency_overrides:
  flutter_web:
    git:
      url: https://github.com/flutter/flutter_web
      path: packages/flutter_web
  flutter_web_ui:
    git:
      url: https://github.com/flutter/flutter_web
      path: packages/flutter_web_ui```

I'm confused about how can "shared code" can really be "shared" across multi-platform in Flutter (shared codebase being the most important feature in Flutter pitch)

Answer 1

正如评论中提到的那样，目前不可能在一个项目中共享Web和本机代码库。如果您遇到过此帖子，请参考this link。它具有Flutter团队可用的解决方法的说明。

Answer 2

我正在研究的一种解决方案是通过dart代理在flutter中使用javascript本机。将您的JavaScript代码复制到Web / src下和index.html文件中。脚本src的javascript代码。在您的main.dart中，将dart：js作为js导入，并使用js.context.callMethod（'your function'，[您的参数]来调用javascript方法。

我也被迫使用javascript，因为flutter不支持chrome的qr阅读器。

Flutter中的Web和Mobile无法共享代码库（？）
