dart - What is the difference between AssetImage and Image.asset - Flutter

Question

In my application, I use these 2 classes but I don't know which one I should prioritize.

Image.asset('icons/heart.png')
AssetImage('icons/hear.png')

Maybe there is one who fetches the image faster.

Answer 1

Image is a StatefulWidget and Image.asset is just a named constructor, you can use it directly on your widget tree.

AssetImage is an ImageProvider which is responsible for obtaining the image of the specified path.

If you check the source code of the Image.asset you will find that it's using AssetImage to get the image.

  Image.asset(String name, {
      Key key,
      AssetBundle bundle,
      this.semanticLabel,
      this.excludeFromSemantics = false,
      double scale,
      this.width,
      this.height,
      this.color,
      this.colorBlendMode,
      this.fit,
      this.alignment = Alignment.center,
      this.repeat = ImageRepeat.noRepeat,
      this.centerSlice,
      this.matchTextDirection = false,
      this.gaplessPlayback = false,
      String package,
      this.filterQuality = FilterQuality.low,
    }) : image = scale != null
           ? ExactAssetImage(name, bundle: bundle, scale: scale, package: package)
           : AssetImage(name, bundle: bundle, package: package),
         assert(alignment != null),
         assert(repeat != null),
         assert(matchTextDirection != null),
         super(key: key);
