Project description:
"I have a nearly-finished shop-billing app written in Flutter. The previous developer estimated that no more than a day of effort is left, but they stepped away before wrapping up a few critical pieces of logic.

What still needs attention
• Tidy up and complete the calculation formulas that drive totals, discounts and tax.
• Harden user-input handling so every figure entered by the cashier is validated and flows correctly through the UI and database.

That’s it—no new payment gateways, inventory modules or authentication changes are required. I simply need someone confident with Dart, Flutter widgets and state management to step in, tighten the code, test the discount & tax scenarios end-to-end, and push a clean, working build back to me.

You’ll get the current source code in a private Git repo, a short checklist of sample bills to run through, and quick feedback as you commit. Once the calculations are accurate and inputs behave as expected, the job is done and I’ll mark it complete." (client-provided description)
