Open-source libraries for Flutter and Dart that we build and maintain. Every package is published on pub.dev under the bangertstudio.kz publisher.
Neatly prepares everything an app needs at launch — server connection, settings, database — and hands it to the screens. Less chaos in the code, easier changes later.
Draws a clear map of the parts a project is made of and how they connect. Helps you quickly understand someone else's or legacy code.
Automatically checks code before a developer adds it to the shared project. Mistakes and sloppy code are caught right away, not after release.
Shows connections between objects as a live interactive diagram — like Obsidian's note graph: nodes can be dragged, zoomed and explored.
Creates test data from the server's description, so the app can be tested without waiting for the backend. Mobile and server parts are built in parallel — the project moves faster.
Helps an app look good on any screen — phone, tablet or computer: the interface rearranges itself to fit the size.
A tool for forms — sign-up, checkout, questionnaires. It shows users where they made a mistake and keeps even forms with dozens of fields reliable.
Records the route even when the app is minimized and sends it to the server. Fits delivery, taxi, courier services and fitness trackers.
Draws the stages of a process as a metro map: parallel branches, where they meet and where it all leads. Fits roadmaps, funnels and task chains.
Checks an app's interface for typical slips — for example, texts nobody prepared for translation into other languages — and produces a report.
Keeps data up to date on every screen: change something in one place and it updates everywhere. Easy to learn, so a new team gets up to speed quickly.
Ready-made checks for form fields: is the e-mail, link, card or phone number entered correctly? Users see the error immediately instead of a rejection after submitting.
Protects transitions between screens from errors: if a screen doesn't get the data it needs, the developer finds out immediately — not the user, as a crash.
A ready-made interface element for choosing from a list — size, city, order status. No need to build such a list again in every project.
Shows all of an app's screens and the transitions between them as a diagram. A handy way to make sure users never get "stuck".
Builds the app's behaviour around clear events — "button pressed", "data arrived". The app behaves predictably and bugs are easier to find.
