How to Add a Messenger-like Chess Game to Your Flutter Chat App

The article provides a detailed guide on integrating a chess game into an in-app chat using the Stream Chat Flutter SDK. It outlines the process of creating a seamless chess-playing experience within a chat interface by adding a chess game as a custom attachment, which avoids cluttering the chat with multiple chessboards. The guide explains how to set up the Stream Chat environment, use the flutter_chess_board package for creating chessboards, and implement a message input widget to trigger the game. It also describes the use of Forsyth-Edwards Notation (FEN) for storing chess game data and details the steps to render a chessboard as a message attachment and update it in real-time as moves are made. The final implementation allows users to play chess directly within the chat, enhancing user engagement without leaving the chat interface.
