Thanks for the feedback!

Firstly, the content is a detailed researched blog integrated with all the source link where it is needed.

Secondly, the link you have shared is just a 1/4 part of the chat app development in Flutter using Firebase. However, my blog is providing a complete overview of the app development right from the market stats of the chat app projecting the future scope to the steps of action to final linking.

Moreover, as far as the plagiarism is the concern, the necessary steps of the development will remain the same. But we have taken this content to the next level by providing a detailed explanation of each point along with sources to help users to understand the entire process simply and easily.

Thanks.
