“无法以声音 null 安全运行”尝试将 Google 地图与 Flutter 一起使用

Question

When I try running Google Maps on Android Studio Emulator I am getting an error message. It does mention some links on where to go on how to solve the problem, but I still don't get it.

The error is:

***

 **Launching lib\main.dart on Android SDK built for x86 in debug mode...**

***

lib\main.dart:1
Error: Cannot run with sound null safety, because the following dependencies
don't support null safety:

 - package:google_maps_flutter
 - package:google_maps_flutter_platform_interface

 - package:stream_transform
 - package:plugin_platform_interface

For solutions, see https://dart.dev/go/unsound-null-safety

Run this command in the project terminal and then run your app.

flutter pub upgrade --major-versions
