hi.
im a .net developer and as unity expert its easy to code with c# for me. as i wanted to start a mobile app, xamarin was my first choice but advises said that xamarin is not performant and its hard to develop for big projects. as i searched flutter and react had upper-hand and with primary tests i found flutter is faster to develop and easier. but the problem starts when with flutter when i want to use a service like firebase, qr reader and... i always have issues with deprecation, build version, not finding resource of package and.... for example for old versions or youtube tutorials the app works well but when i use old versions i just get deprecation messages and when i use latest versions i get message like "Your application could not be compiled, because its dependencies could not be established."
i believe working outside of visual studio and microsoft solutions can be a hell.
i just asking for exprience. is xamarin still a bad idea to work with????
