如何从 Android Studio 运行 在 Windows 10 上构建 运行ner

How to run Build runner on Windows 10 from Android Studio

我正在关注 Google 的 Flutter Googlemaps 代码实验室,

https://codelabs.developers.google.com/codelabs/google-maps-in-flutter/#5

G 实验室说

Once you've added this code, your IDE (if you are using one) should display some red squiggles, as it references a nonexistent sibling file, locations.g.dart. This generated file converts between untyped JSON structures and named objects. Create it by running the build_runner:

Build runner 应该输出这个:

$ flutter packages pub run build_runner build
[INFO] Generating build script...
[INFO] Generating build script completed, took 291ms

[INFO] Initializing inputs

我不知道该怎么做。在他们控制台的打印中,光标克拉是一个 $,Android Studio 控制台在 windows 10 上没有出现,所以....混乱。

这是请求的 .yaml 文件

environment:
  sdk: ">=2.1.0 <3.0.0"

dependencies:
  flutter:
    sdk: flutter
  google_maps_flutter: ^0.5.11
  http: ^0.12.0+1
  json_serializable: ^2.0.2


  # The following adds the Cupertino Icons font to your application.
  # Use with the CupertinoIcons class for iOS style icons.
  cupertino_icons: ^0.1.3

dev_dependencies:
  pedantic: ^1.4.0
  build_runner: ^1.2.7
  flutter_test:
    sdk: flutter

@i6x86 正确诊断了问题,我没有完全设置 Flutter。我按照此处的说明操作:flutter.dev/docs/get-started/install/windows#update-your-path

重新启动 Android Studio 瞧,它解决了问题。
