What do I mean??
I am talking about the ui of your app. If you are a webdev or an app developer ( not the one with figma) and you struggle with your designs hear me out. There are a lot of design trends in the ui realm and it's a mess. Like the material or the Cupertino, etc.. and it's hard to implement. (Yes, in flutter it's quite simple but)Some functionality or widgets by our apps needs to be different and you can't find a widget or a component for that and you can't find it , so naturally you try to combine different widgets and nothing works here's what you wanna do.

1) Create your own widget/component
I mean your own. Why not just keep it simple and clean
2) Large apps are not strict followers of themes
For example take the ui of YouTube or instagram, do they follow stylish or extra flashy UI. No usability > style. Think about it
3) Don't follow the themes you see on Instagram.
There are lot of flashy themes created with UI design softwares and some of them are actually good. But yours is too. The only way you can improve is by trying
