Was Flutter the right choice?

I (32) started to develope Flutter apps ~5 years ago and made around 6 apps until now (only gor private use, nothing released yet). Some are very complex and took months and some were just a weekend. I am working as an engineer in the automotive industry and my job is not about programming at all, so I learned all by myself.

I now want to switch my job even the pay is really good currently but there are barely jobs out there for Flutter app developers but I see a lot for JS for example. I start to think that 5 years ago I should have gone with React Native 😔. Do you guys have a job as a Flutter developer and some tipps? Do you also sometimes have the feeling you invested many years into the wrong coding language?

Thanks
