[Solved] pubspec.yaml: A package may not list itself as a dependency.

When I got this issue ?

This error I got for url_launcher package. But actual issue is when the dependency you have added and the project name of yours is exactly same then you will encounter this issue.

My dependency with error:

pubspec.yaml

name: url_launcher
description: A new Flutter project.
dependencies:
  url_launcher: ^5.5.0
  flutter:
    sdk: flutter  

Fix

Fix is very simple, you just need to rename your project.

Working code for your reference:

pubspec.yaml

name: url_launcher_demo
description: A new Flutter project.
dependencies:
  url_launcher: ^5.5.0
  flutter:
    sdk: flutter
