NOOK

Pet care app in Flutter

A pet care day planner in Flutter. Each pet sits in a nook inside a 24 hour dial of meals, play, water and medicine, and every meal is weighed on a kitchen scale.

Stack: Flutter 3.47, Riverpod, go_router
Runs on: iOS and Android
Screens: 6, plus launch and splash
Art: Mochi and Bobo, drawn for the app
Tests: 16 passing, 0 analyzer issues
Code: 66 Dart files, no comments

Mochi and Bobo were drawn for this app and come with the code. Fonts under the OFL, icons by Lucide under ISC

Watch it run

Filmed from the real app, beside its real code.

Mochi peeks from the nook while the knob sweeps a whole day round the dial
Tap the pet and it hops, finish a task and its mark turns ink as the bar fills
Each tab rises from below and its icon hops in the dock
Weight bars grow, doses fill with a pop and the vet card flips to its note
The calorie needle swings to the total for the day
The scale opens as a circle out of the paw button
The scale needle follows your finger on a spring
A check stamps the dial and FED! drops in letter by letter

Every screen

Day
Log meal
Fed
