How to use local flutter package in another flutter application?

I created a package using following command:

flutter create --template=package my_new_package 

and then in my application source code => main.dart

import "package:my_new_package/my_new_package.dart" // can not find the package 

Answer 1

Find this file in your flutter application => pubspec.yaml

Use local dependency

    dependencies:        flutter:          sdk: flutter        my_new_package:          path: ./my_new_package 

Note: The ./my_new_package above means that the my_new_package directory containing the pubspec.yaml for the package is a sub-directory of the app.

If you have the package as a directory at the same level as the app, in other words one level higher up in the directory tree, you can use ../my_new_package (note the double dot) or a full path to the package directory.
