package not found - Target of URI doesn't exist

[arizvi-techgies]

I am using the below in my main.dart, I have tried cleaning and rebuilding, closing and reopening the vs code, and uninstalling and reinstalling the package. All other packages are working except this one.

import 'package:flutter_animate/flutter_animate.dart';

My pubspec.yaml

environment:
  sdk: '>=3.2.0 <4.0.0'
dependencies:
  flutter:
    sdk: flutter
  google_fonts:
  local_auth:
  riverpod:
  flutter_secure_storage:
  flutter_animate: ^4.2.0+1
  material_design_icons_flutter:
  flutter_native_splash:
  http:
  openapi_generator_annotations: ^4.11.0
  flutter_platform_widgets: ^5.0.0

I closed and reopened the Vscode, and some black magic happened, and it is working now.
