Canton UI

Canton UI elements and resources for Flutter.

Examples in Apps

Notes App	News App	Elisha

Description

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 pub.dev in the near future.

Getting Started

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

dependencies:
    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 :)

Using

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.

CantonApp

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

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

CantonScaffold

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

CantonScaffold(
    body: Column(
        children: [...]
    )
)

Colors

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.

CantonColors.blue

CantonColors.pink[300]

CantonDarkColors.green

ViewHeader

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

ViewHeaderOne(
    title: ...,
    button: ..., // Placed on right side
)


ViewHeaderTwo(
    title: ...,
    backButton: ...,
    isBackButtonClear: ...,
    buttonOne: ...,
    buttonTwo: ...,
)

Buttons

CantonUI has a lot of different buttons to choose from.

ActionButton()

BackButton()

HeaderButton() // Commonly used in ViewHeaders

NullButton() // Great spacer widget

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

TextInput

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

CantonTagTextInput()

Loading

Default Loading Spinner

Loading()

RefreshList

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.

RefreshList(
    child: ...
)

Responsive

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.

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