Now project is being at the very early prototype stage.
In fact, it is a parallel version of the music player that I started a year ago. My decision to switch to flutter with a native android development is multi-platform and more simple and convenient code writing, but this does not mean that I will abandon the previous project.
First, as last time, I plan to make a working model of the player, after which I will add functions of telegram client using flutter TDLib package.
