I built an expense tracker app using Flutter a while ago that I've been using for a year. It has really helped me in understanding where my money is going. To build it quick, it uses Google Sheets as a backend and BigQuery for running sql queries over the data. While everything works, it's quite slow so I'm looking at building the API server with rust warp and sqlite to store all transactions.
How easy are you using flutter to use so far? I have been thinking about learning about flutter for a long time, but still unsure about how much support is there in terms of 3rd party libraries, and whether that can hinder development at some point.
