Stop rebuilding
the same widget.
A Flutter kit of components that already know what your app looks like. Style them once, and every button, field and table follows — on phones, tablets and the web.
Components
Everything is an Up.
One prefix, one set of conventions. If you can guess the Flutter widget you want, you can guess ours — and they all read their look from the same place. Anything underlined below opens its page in the docs, with a live example you can poke at.
30 components, plus dialogs, helpers and validators.
Beyond the widgets
The parts you would have written anyway.
A component library that stops at components leaves you to build the same scaffolding on every project.
UpStyle and UpThemeData describe how things look; every component reads from them. Change the theme, not thirty widget calls.
UpResponsivePage and the layout service handle the phone, tablet and desktop cases, so one build serves every form factor.
Navigation, dialogs, search, URLs and scaffolding come as services — the plumbing every app needs and nobody enjoys writing twice.
Clipboard, toasts, date and time formatting, validation and encryption helpers — small things, each of which otherwise costs an afternoon.
The details
Open source, and on its fifth major version.
Flutter Up is MIT licensed and developed in the open. Read the source, file an issue, or fork it. The documentation at flutterup.dev is itself a Flutter app built with Flutter Up — so every example on it is the library running, not a screenshot of it.
