Loading GIFs

High quality Android and iOS loading spinners.

View Demo

Loading GIFs is a collection of high fidelity loading animations in GIF format. Included are Android "Material Design" and iOS "Cupertino" default loading indicators.

Usage

Import this library into your project:

loading_gifs: ^latest_version

Use cupertinoActivityIndicator or circularProgressIndicator where ever a loading image is needed.

FadeInImage.assetNetwork(placeholder: cupertinoActivityIndicator, image: "image.png");

That's it!

Usage Tips

Size

This library is optimized for size so it only includes the base asset sizes. Change the size of the loading spinners using scale and placeholderScale.

FadeInImage.assetNetwork(placeholder: cupertinoActivityIndicator, image: "image.png", placeholderScale: 5);

Image.asset(circularProgressIndicator, scale: 10);

Dynamic Images

When loading images whose dimensions are unknown ahead of time, use cupertinoActivityIndicatorSmall instead of cupertinoActivityIndicator. cupertinoActivityIndicatorSmall is a min height variant of cupertinoActivityIndicator which allows Flutter to correctly expand the loaded image into the layout.

The small variant should be used when loading a list of images or compositing an image from multiple images.

  ListView(
    children: <Widget>[
      FadeInImage.assetNetwork(
          placeholder: cupertinoActivityIndicatorSmall,
          image: "image_1.png"),
      FadeInImage.assetNetwork(
          placeholder: cupertinoActivityIndicatorSmall,
          image: "image_2.png"),
      FadeInImage.assetNetwork(
          placeholder: cupertinoActivityIndicatorSmall,
          image: "image_3.png"),
    ],
  )

Empty Placeholder

FadeInImage requires a valid placeholder image to avoid "Asset not found" errors. Use placeholderEmpty, a 1x1 pixel transparent PNG, when an empty placeholder is needed.

FadeInImage.assetNetwork(placeholder: placeholderEmpty, image: "image.png");
