Flutter build error.(related to pub-cache)

Question

When I tried to build my project, I get this error printed in my console.

everything was working fine 2 days ago.

Here is the error,

Running "flutter pub get" in SampleApp...
Launching lib\main.dart on Android SDK built for x86 in debug mode...
/E:/flutter/.pub-cache/hosted/pub.dartlang.org/firebase-7.3.0/lib/src/top_level.dart:1:8: Error: Not found: 'dart:html'

FAILURE: Build failed with an exception.

* Where:
Script 'E:\flutter\packages\flutter_tools\gradle\flutter.gradle' line: 896

* What went wrong:
Execution failed for task ':app:compileFlutterBuildDebug'.
> Process 'command 'E:\flutter\bin\flutter.bat'' finished with non-zero exit value 1

* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output. Run with --scan to get full insights.

* Get more help at https://help.gradle.org

BUILD FAILED in 4m 13s
Exception: Gradle task assembleDebug failed with exit code 1
Exited (sigterm)

I really don't know why is this is happening, i tried googling but couldn't find anything useful.

There are more errors, related to .pub-cache, but i didn't post it, as then the question would be too long.

Please help.

The error is in the "Firebase" package, remove that, and it's working.

To be specific on what needs to be done to help others who are seeing this issue , I am explaining it below :

When you somehow add below import statement, you are likely to see this issue :

import 'package:firebase/firebase.dart';

Find and remove above line, clean your build (by running flutter clean command) and run again. Issue should be resolved by now.
