fitbit-color-themes 🎨

Description:

This code automates the use of color-themes in fitbit apps.

You only need to define your themes and add a corresponding class to your elements, you want those colors be assigned to. The last chosen theme gets saved and reused on reload of the app. The first color of each theme gets written to your app's settings-page.

This repo is written in ts for SDK 5.0.2.
A javascript version will follow, or you might adjust the code by removing types.

Installation:

• app:
  Copy the folder app/color_themes into your app directory
  
  app/index:
  

import {initColorThemes} from "./color_themes/applyColors";
initColorThemes();

• common:
  Copy the folder common/color_themes into your common directory.
  

• companion:
  Integrate the code in companion/index.ts into your index file.

  (You can also download a template and start your project from there.)

Usage:

Define your array of color-themes in common/color_themes/colorThemes.ts like in the following example (no matter how many themes, or how many colors per theme):

const themes :string[][] = 
[
    ['tomato', 'blue', 'yellow'],
    ['sandybrown', 'white', 'grey'],
    ['gold', 'limegreen', '#000000'],
    ['aquamarine', 'turquoise', 'yellow'],
    ['deepskyblue', 'blue', 'red'],
    ['plum', 'magenta','white'],
];

To store/restore the last chosen color-theme, it gets written to a *.cbor file in

common/color_themes/shared_preferences.js . Give this file a unique name.

(I here took the UUID of my app + _fct.cbor.)

const FILE_NAME = "f100f76b-0a9e-488f-ba35-d1a8531a2d4b_fct.cbor";

The elements you want to be filled with a color of your themes need to be classed in resources/index.view like the following example:

<svg>
    <rect id="myElement1" class="color0" width="100%" height="100%" x="0" y="0" />
    <rect id="myElement2" class="color1" width="10%" height="10%" x="100" y="100" />
    <circle class="color2" cx="80%" cy="50%" r="20%"  />
</svg> 

Now having x colors per theme, all fills get applied to the elements with

class = "'color' + (0 to x-1)"
The first color of each theme gets automatically implied in your app's setting-page - and done.
