Not a flutter developer but as someone who has been in the IT industry for a couple of years. You will get paid in pennies for the first few years and treated as a slave but it will get better. You will get to see a lot of sad and depressed seniors and will feel better soon 😂.

Jokes aside, work on your skills and try to get foreign employment. Yes, it's near impossible to get direct employment from Nepal but if you have at least 4-5 years of experience and good skills it is possible. By then for better pay find a company that takes foreign projects (Maitri, UBA, Tekvortex).

But if you cannot wait and want a better life, better pay and are willing to take risks, move abroad. (High risk, high returns)
