Flutter 101 app for iPhone and iPad

As a developer, like me, we are lacking in our sense of visual things.
It is really hard to determine which one is better than the other. Honestly, I have no sense of it at all.
One day, an idea popped up.

"What if all kinds of visuals such as fonts, icons, and so on, are listed up on my mobile display? It would be wonderful for me."

This application was started from the idea.
For small developing teams and independent developers, I’d like to show what fonts and icons are available to use and what they look like.
I hope that this app would be helpful for you in getting what you want.
