universal_image

A comprehensive image package that provides a unified solution for displaying all major image formats across mobile, desktop, and web platforms in Flutter applications.
Skip the hassle of Image.network(), Image.asset(), or Image.memory() - simply pass your image source and let UniversalImage handle the rest

Key Features

• Supports a wide range of image formats, including JPEG, PNG, GIF, Animated GIF, WebP, Animated WebP, BMP, and WBMP from the built-in Image widget.
• Seamless integration with flutter_svg for rendering SVG images.
• Powerful caching capabilities with extended_image for optimal performance.
• Streamlined usage with imageUri, eliminating the need to specify network, asset, or file paths separately.
• Ability to work with Icons font and memory-based images.

Example usage:

• Assets provider

    var image = UniversalImage(
      'assets/image.png', // path must start with 'assets'
