Flutter 在使用 Google Maps Platform 时抛出 SecurityException

Question

1-.使用案例。

我在 Flutter 和 Dart 项目中使用 google_maps_flutter 包。版本是 google_maps_flutter: ^2.4.0

当我在 Flutter 中调用 GoogleMaps 小部件时：

抛出以下 SecurityException：

2-.已实施 API 密钥

我遵循了 google_maps_flutter 包 (https://pub.dev/packages/google_maps_flutter) 中描述的指南，即在 Flutter 中安装 Google Maps SDK 的指南 (https://developers.google.com/maps/flutter) -package/config?authuser=0#step_1_install_the_required_software），以及“Maps SDK for Android Quickstart”文档 (https://developers.google.com/maps/documentation/android-sdk/start) ->

i) 生成 GMP API 密钥 与Maps API相关的api key是第四个 ->

…使用以下 api 密钥 ->

...和限制 ->

ii) android manifest.xml 是 ->

   defaultPropertiesFileName = "local.defaults.properties"


   // Configure which keys should be ignored by the plugin by providing regular expressions.
   // "sdk.dir" is ignored by default.
   ignoreList.add("keyToIgnore") // Ignore the key "keyToIgnore"
   ignoreList.add("sdk.*")       // Ignore all keys matching the regexp "sdk.*"
}

3. 预期结果

尽管抛出异常，但地图在通过 USB 连接的设备中正确呈现。 如果生成apk并安装到设备上，则不会渲染地图，并抛出异常。

4. 您尝试使用其他设备吗？

是的。我在 SMA426B 和 MiT11 中验证了这个过程

Answer 1

您还需要添加INTERNET权限，将此行添加到androidManifes.xml

<uses-permission android:name="android.permission.INTERNET" />
