Overview:

The @polkadot/ui library provides basic browser and framework agnostic UI components for creating apps using the polkadot{.js} libraries. It includes various components such as identity icon generators, a QR code generator/reader, and shared libraries for browser-specific functions like keyring and local storage.

Features:

• React Identicon: Generates a unique identity icon using React, with the address as input.
• React Native Identicon: Generates a unique identity icon using React Native, with the address as input.
• Vue Identicon: Generates a unique identity icon using Vue, with the address as input.
• React QR: Generates and reads QR codes specifically for uos (Substrate/Polkadot only).
• UI Keyring: A browser-specific wrapper around the base @polkadot/keyring library, for managing keyrings.
• UI Settings: A browser local storage wrapper for app settings and configuration.
• UI Shared: Shared logic that is used across UI components, such as for icon generation.
