What salary should I expect?

So first thing first, im a mobile app dev. Ive worked on various tech : flutter, android, some backend shit. I have apps on around 100k devices.

I have a total exp around 2.2 yrs (including 7 months intern)

I'm currently having a package of 3 lpa :(. How much should i expect? And how do i get one? Hard to find connections though.

The reason of this ctc is Im from small city.

Well i do have offer of 6.5 lpa. Is it justifiable ? . Can u tell me how much should i expect from my next switch?
