>Since Flutter is newer and uses a less popular language there's many more questions about Flutter. This is totally expected.
It's more complicated than your proposed cause & effect. A counterexample is that Rust is much newer than C++ and yet C++ still has higher volume of questions using Stackoverflow's trending tool:
This matches real world observation that C++ is still more popular and widely used than Rust.
I don't have the raw data but I'm guessing that even if Stackoverflow compared Flutter-vs-ReactNative # search queries instead of # of questions, Flutter would still have a higher count.
Sorry, the two year lead that Flutter has, and still being close to React Native in terms of subscribers implies React Native was picked up quicker or is more popular.
However, I do agree that RN has the momentum and familiarity of React as tailwinds.
