lilian_cached_network_image 1.0.1

A Flutter package for caching network images.

lilian_cached_network_image

A Flutter package for loading and caching network images using a hybrid strategy: instant load for small images via SQLite blobs, and file system storage for larger images.

This package combines the strengths of flutter_cache_manager with a high-performance SQLite-based blob caching system.

Features

• Hybrid cache: Images ≤ 50KB are stored in SQLite as blobs for nearly instantaneous loading.
• File system storage: Larger images are stored in the file system using flutter_cache_manager.
• Built-in Shimmer loading: Includes a shimmer effect during image loading.
• Fade transitions: Smooth fade-in transitions once the image is ready.
• Highly Customizable: Custom placeholder builders, error builders, and cache managers.

Installation

Add this to your pubspec.yaml:

dependencies:
  lilian_cached_network_image: ^1.0.0

Usage

Widget

import 'package:lilian_cached_network_image/lilian_cached_network_image.dart';

LilianCachedNetworkImage(
  imageUrl: 'https://example.com/image.jpg',
  width: 200,
  height: 200,
  borderRadius: BorderRadius.circular(12),
  useShimmer: true,  // default
)

ImageProvider

CircleAvatar(
  backgroundImage: LilianCacheImageProvider(
    'https://example.com/avatar.jpg',
  ),
)

Configuration

You can configure global cache settings:

LilianCacheManager.setup(
  stalePeriod: Duration(days: 7),      // default
  maxNrOfCacheObjects: 200,            // default
  blobThreshold: 50 * 1024,            // 50KB - threshold for SQLite blobs
);

Platform Support

• Mobile/Desktop: Supports both SQLite blob storage and file system caching.
• Web: Uses file system caching (SQLite is not available in standard browser environments).
