Canton UI

Canton UI elements and resources for Flutter.

Examples in Apps


This includes things such as themes (colors, typography, etc.), custom methods, buttons, text-inputs, a color picker, and more. This all in attempt to limit the amount of time I spend on remaking simple tools and ui, while still customizing my screens to my flavor. Please note that this package will not be uploaded on in the near future.

Getting Started

To use this package and access its content, add this dependency to your pubspec.yaml

    canton_ui: <latest_version>

And simply import the package using this code

import 'package:canton_ui/canton_ui.dart';

BTW package:flutter/material.dart is already imported when using this package so no need to re-import ?


Note: The package is versatile in a sense that you do not have to use all of the elements in the package. You can mix it in with Material and Cupertino elements with no problem with the exception of certain elements.


Replaces MaterialApp. Recommended that you use this over MaterialApp to get you the theming and lightmode/darkmode switching.

    title: kAppTitle,
    primaryLightColor: // Or any other color,
    primaryLightVariantColor:[200]! // Or any other color,
    primaryDarkColor: // Or any other color,
    primaryDarkVariantColor:[200]! // Or any other color,
    home: YourMainAppWidget(),


Use this as a replacement for Scaffold() widget. Adds padding and other elements.

    body: Column(
        children: [...]


You can view all the colors at lib/config/themes/(light_theme or dark_theme)/(light or dark)_color_palette.dart

Using colors directly is discouraged and should be accessed through Theme.of(context).colorScheme

This is to allow the light and dark colors to be used in the correct situation (When app is in light mode or dark mode). Exceptions to this rule do apply, for instance when setting up CantonApp.[300]


Instead of using a navbar, CantonUI uses a ViewHeader, in which you can customize the leading and action buttons

    title: ...,
    button: ..., // Placed on right side

    title: ...,
    backButton: ...,
    isBackButtonClear: ...,
    buttonOne: ...,
    buttonTwo: ...,


CantonUI has a lot of different buttons to choose from.



HeaderButton() // Commonly used in ViewHeaders

NullButton() // Great spacer widget

PrimaryButton() // Default button, great for all use cases, highly customizeable


CantonUI offers a standard text input and a tag text input field (Used in the note taking app). Both inputs are highly customizeable and it’ll look good right out of the box.

CantonTextInput() // obscureText is required if isTextFormField is true



Default Loading Spinner



If you’re making an app in which pull to refresh is needed (like a news app or an app that needs to call an API) then this widget has you covered.

    child: ...


If you need to create a UI that’s needs to compensate for different screen sizes, then you can use the Responsive widget to take care of it.

Note: mobile and tablet are required.

    desktop: YourDesktopWidget() // Screens larger than 1100px width,
    tablet: YourTabletWidget() // Screens between 650 - 1149 px width,
    mobile: YourMobileWidget() // Screens between 0 - 649 px width,
