Create Skeleton Loader component #4858
Description
Describe the solution you’d like
Add a built-in Skeleton Loader component to react-native-paper that can be used as a placeholder while content is loading.
The component should align with Material Design principles and the existing Paper theming system (colors, dark mode, shape, animation preferences).
Describe alternatives you’ve considered
Currently, skeleton loading is typically implemented by:
Using third-party libraries (which may not integrate well with Paper’s theme system), or
Manually composing View components with animated opacity/backgrounds, which leads to duplicated, inconsistent implementations across apps
Neither approach feels ideal for a UI library that already provides polished, opinionated components.
Additional context
Many modern design systems include skeleton loaders as a standard pattern, and they are increasingly preferred over spinners for content-heavy screens. Having this as part of react-native-paper would improve developer experience and visual consistency across applications using the library.
