You are not the only one -- I've been developing in Flutter for the past couple of months and overall I'm very satisfied how easy it is to develop in it compared to native Android and iOS. Being native Android dev, I truly believe that there is a future in Flutter. Till now I was rejecting all the other cross-platform frameworks.

Big part of it is thanks to the community which is providing all the handy packages to add some native stuff easier (such as permission, localization etc.)

I agree with other comments that Flutter Web is not ready yet I've tried to build web version for wish list sharing based on Flutter and I was struggling, so in the end I've switched to Tailwind + Vue. Some issues I had was that website didn't behave like website. For example I couldn't select text with my mouse. It felt and behaved more like a mobile app through the browser.

For mobile though it works (almost) perfectly, my example of the mobile iOS and android app build with Flutter: https://wishpy.com/

Although it loads a bit long at the beginning and I still need to figure out how to show images and icons without an uncomfortable glitch at the screen start.
