Depends. If it's a hobby, learn both to be more valuable.
If it's for a business? How much money do you have to throw away? Does the app pay for itself, or is it a cost centre? (99.9998% of the time, it's a cost centre.)
You really asked the most boring part of that question. Most of the answers below suggest that the app is defending its territory, etc. Malarkey.
Just like you're not winning the lottery, you're not writing a standalone app that can pay for itself.
Why? Hundreds of thousands of apps exist on each platform right now.
For your app to stand out enough to be successful it needs synergy with something. A web site, a service, a IRL business.../something/.
Tha says to me: do the cheapest possible thing. If you have React devs, use that. If you don't, find the alternative cheapest possible way. Flutter? Maybe. Nocode (like Glideapp, https://www.nocode.tech/category/app-builders)? Maybe.
Pick the fastest/cheapest way to get an app out to validate the concept. Once validated, then you'll have enough information to know what pain points you have, and what solutions you /really/ need.
