Flutter: [ERROR:flutter/lib/ui/ui_dart_state.cc(209)] Unhandled Exception: PlatformException

Question

I am new in Flutter. I face a problem about [ERROR:flutter/lib/ui/ui_dart_state.cc(209)] Unhandled Exception: PlatformException.

Here is my Debug Console:

Launching lib\main.dart on sdk gphone x86 in debug mode...

How do I fix it?

This error is caused when you are not connected to internet. Check your internet connection and try again.

Check if you have added INTERNET permissions in the androidManifest file.
From the logs I can see that you are using google_sign_in so make sure you have uploaded the SHA-1 to the Firebase console. If not then add the SHA-1 key and replace your google-service.json file with new one.
If running on an emulator check if the emulator can access the internet. More on this here.

I checked the Internet, the Internet is stable. – My Car Nov 28 '21 at 05:47
I uploaded the SHA-1 key and replaced my google-service.json file with new one, but the problem still here. – My Car Nov 28 '21 at 06:43
@MyCar is it a release version or debug version apk and is it running on a emulator on real device? – Ashutosh Patole Nov 28 '21 at 06:56
It is a debug version apk. – My Car Nov 28 '21 at 07:01
It is running on a emulator on the computer. – My Car Nov 28 '21 at 07:05
So check if the emulator can access the internet. There's the problem. Made an edit on the answer. If it solved then do accept and upvote :) – Ashutosh Patole Nov 28 '21 at 07:26

Open Settings in your Emulator

google is rejecting your request because your API is not enabled, enable maps SDK for android and IOS, then add your API key in the AndroidManifest.xml
