【问题标题】：Flutter google maps widget throws an errorFlutter 谷歌地图小部件抛出错误
【发布时间】：2021-08-11 12:25:29
【问题描述】：

我是 Flutter 的新手，我不必运行 Google Maps Widget。我将不胜感激任何帮助。谢谢！ 我已经修改了 pubspec.yaml 文件以及 appdelicate.swift，插入了 google api 的 android manifest 文件。 I hope that this should mean that API is enabled 这是我的代码https://github.com/Vilumsy/kalle_first。

错误：

    【解决方案1】：

    错误很清楚吧？ 未处理的异常：PlatformException(错误，未找到 API 密钥

    您需要添加一个 meta-data 标记，其中包含 application 标记内的 google map api 键，如下所示 AndroidManifest.xml 文件

    AndroidManifest.xml 文件位于 your_project_folder/android/app/main 文件夹中。将以下元标记放在 application 标记内。

    注意：您需要从 google 控制台获取 google map api 密钥

       <meta-data
        android:name="com.google.android.geo.API_KEY"
        android:value="YOUR_API_KEY" />
