I'm still improving myself with Android (Java and Kotlin) but then I wanted to also try Flutter, seems promising for me.
I agree with others too, maybe try both pero ihuli mo na po ang flutter then from there, if parehas mo nang nasubukan, decide if alin po mas gusto/trip mong gamitin
Before yung gamit ko is yung Android Studio, Then Thesis namin is gumamit naman ako ng React Native for the mobile app then sa work ko front-end flutter dev ako non. hahaha So far mas marerecommend ko yung flutter, pero I think both okay sila. Depende nalang sa paggamit mo.
