universal_image

A universal image package to display all image types for all platforms (mobile, desktop and web)

General

• It does supports JPEG, PNG, GIF, Animated GIF, WebP, Animated WebP, BMP, and WBMP from Image
• For SVG, it uses flutter_svg
• It also supports caching image with extended_image
• It can handle all providers without specifying network, assets or file, just use imageUri
• It can work with Icons font & memory image as well

Example usage:

• Assets provider

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

      scale: 1.0,
      width: 100,
      height: 100,
      frameBuilder: null,
      errorBuilder: null,
      semanticLabel: null,
      excludeFromSemantics: false,
      colorBlendMode: BlendMode.clear,
      fit: BoxFit.cover,
      alignment: Alignment.center,
      repeat: ImageRepeat.noRepeat,
      centerSlice: Rect.fromLTWH(0, 0, 100, 100),
      gaplessPlayback: false,
      isAntiAlias: false,
      filterQuality: FilterQuality.low,
      cacheWidth: 100,
      cacheHeight: 100,
      allowDrawingOutsideViewBox: false,
