Components
Added the following design changes to all components: color change, shadow, padding, and opacity changes. All changes are according to the new formats.

Badge

Added a variant with icon.
Pseudo Props for Color Modes
Updated theme using _light and _dark props for light mode and dark mode respectively.
Internal props will still have higher specifity, as it will override platform props as well as color mode props.
Theme Decoupling
In 3.4 we have completely decoupled the theme. All the internal design props are now transferred to the theme.
This will allow you to use multiple theme files in your project and toggle between them efficiently.
Extend previous version's theme for backward compatibility
You need to add v33xTheme to your NativeBaseProvider which preserves all the old design that was changed or removed in v3.4.0.
Copy
import { NativeBaseProvider, extendTheme, v33xTheme } from 'native-base';
// ...
const yourCustomTheme = {
// ...
};
<NativeBaseProvider
theme={extendTheme(v33xTheme, yourCustomTheme)}
></NativeBaseProvider>;
