codezinfinity/Paisa ? reverse-engineered prompt

Build me a clean Material Design expense tracker app called Paisa for Flutter.

I want it to let users track expenses, income, and deposits, then show a simple overview by account, budget, and category. The app should work nicely on phone, tablet, foldable, desktop, and web, with a polished responsive layout. Include screens for home, accounts, categories, and budget overview, plus a way to add and manage transactions and view spending at a glance.

Please make it feel modern and easy to use, with good spacing, clear charts or summaries if needed, and support for multiple languages through localized text files. Keep it production ready and consistent with the existing Material style. If you need to look up current Flutter docs or best practices online, go ahead.
