dali 0.0.12

A fast and efficient image downloading and caching library for flutter. Supports iOS and Android

Dalí

An image loading and caching library for flutter focused on speed and memory efficiency.

Supports iOS and Android.

Dalí saves the downloaded image in memory in case the same image is requested in the future. Only a resized version with the desired size will be loaded in memory instead of loading the full size in order to preserve RAM memory.

Images are also saved in the cache directory of the app.

Getting Started

Use the Dali widget

The easier way is to use the Dali widget. It will get the dimensions of his container and load a resized image

Container(
  height: 200,
  width: 200,
  child: Dali(
    'https://homepages.cae.wisc.edu/~ece533/images/airplane.png',
  ),
)

You have the option to set a loading widget while the image is being loaded, and also an error widget if it occurs

Dali(
  imageUrl: 'https://homepages.cae.wisc.edu/~ece533/images/airplane.png',
  fit: BoxFit.cover,
  placeholder: Icon(Icons.timer),
  errorWidget: Icon(Icons.error),
)

Use the DaliImageProvider

Alternatively you can use the DaliImageProvider in combination with the Image widget

Image(
  image: DaliImageProvider(
    'https://homepages.cae.wisc.edu/~ece533/images/airplane.png',
    width: 90,
    height: 90,
  ),
  fit: BoxFit.cover,
)

Remember it is always better to set the width and height of the image
