Theme

Overview

The Theme is a style applied to every component of CometChat. When a style is applied as a theme, every view in the activity or every component in the UiKit will apply each property of the theme that it supports.

CometChat theme comprises two key components: Palette and Typography.

Palette: The Palette can be used to customize the color scheme of the CometChat theme, including background color, primary and secondary colors, error color, and various levels of accent colors.

Typography: Typography, which is also a singleton class, encompasses all the default Text Style’s values. It allows you to customize the text appearances throughout the CometChat theme, such as heading, name, titles, subtitles, text, and captions.
