My app build failed with the following build error:
√ Built build\app\outputs\flutter-apk\app-debug.apk.
D/FlutterLocationService(29765): Creating service.
D/FlutterLocationService(29765): Binding to location service.
Error connecting to the service protocol: failed to connect to http://127.0.0.1:51234/v9-zOlh23aE=/
Exited (sigterm)
this happened after pub upgrade.
Though this issue seems to be common and can be caused by various situations, maybe you should check whether the SDK is selected.
In Android Studio, you can set the SDK in File -> Project Structure -> Project SDK, which works in my case.
Or else you can also try flutter clean && flutter upgrade.

The error is caused due to outdated packages in your flutter project.
To solve the errors, do the following :
Step 1: Run the command flutter pub outdated in the terminal of your development environment. This command will find and display the list of packages that can be updated.
Step 2: Run the command flutter pub upgrade in the terminal of your development environment. This command will update the outdated packages.

There is no artifact, so probably build failed. You should check your debug console to see what is the exact problem.
I have added the flutter webview plugin but its causing problems. Its giving some error when building the project. I tried to delete the cache and rebuild the project but it didn't work.
