Create a new Flutter package project in Android Studio

Flutter Package Project

After creating project structure will somewhat look like this unlike normal flutter project.

By Default the file name will be created based on the package name you given when creating the flutter package project

I have created the flutter package by sample_text

i’m going to create package of CustomText

Created a CustomText stateless widget

Why I have created this widget ?

When the project size goes bigger and bigger it will be quite difficult to write Text(“”, style=TextStyle()) this widget’s TextStyle again and again fo many times so that’s y I have created a CustomText stateless widget.

Try running flutter packages pub publish — dry-run in your terminal

This command is to check whether any warnings or errors coming in our package

So here I got 2 warnings lets solve those warnings

  1. Create a git Repository and push your project in the github
  2. Remove the author from pubspec.yaml file
Remove the author key from pubspec.yaml

Next after doing the 2 steps add the git repo link in pubspec.yaml

Don’t forget to run pub get

Your pubspec.yaml file somewhat looks like this

Now try running flutter packages pub publish — dry-run in your terminal

You won’t get any warnings

And most importantly update your licence or else you won’t be able to upload the package

Run flutter packages pub publish in your terminal

You will get a succesfull upload message

And you are ready to go 🚀🚀
