Flutter or Web development

Question

I’m unable to choose between learning more about flutter or continue in this fronted development certificate I’m doing, that teaches everything from scratch like html css JS react and everything . I used flutter for some projects but i feel if i want to be a real developer i should have knowledge about JS and the others.
So i need some advices please.

Answer 1

why not both?

Answer 2

Absolutely agree with Bob_Li ...
Why not explore Mustafa Mansuor ... You obviously have some experience with Flutter so why not add to your arsenal and increase your value to self by adding new skillsets and to future employers seeking someone who is versital and can jump from one project to the next ( just needing the project specifications ).
