cached_memory_image

pub package

A Flutter library to show images from the Base64, Uint8List and keep them in the cache directory.

Features

Check file is exists
final cachedImageManager = CachedImageBase64Manager.instance();

await cachedImageManager?.isExists('app://image/1');
await cachedImageManager?.removeFile('app://image/1');
Cached Image from Base64
  • Widget
CachedMemoryImage(
  uniqueKey: 'app://image/1',
  base64: 'iVBORw0KGgoAAAANSUhEUgAAAk0AAAFwCAYAAACl9k...',
),
  • Image Provider
CachedMemoryImageProvider(
  'app://image/6',
  base64: 'iVBORw0KGgoAAAANSUhEUgAAAk0AAAFwCAYAAACl9k...',
)
Cached Image from Uint8List
  • Widget
CachedMemoryImage(
  uniqueKey: 'app://image/1',
  bytes: Uint8List.fromList([1,2,3,4,5]),
)
  • Image Provider
CachedMemoryImageProvider(
  'app://image/5',
  bytes: Uint8List.fromList([1,2,3,4,5]),
)

Getting started

It is really easy to use! You should ensure that you add the cached_memory_image as a dependency in your flutter project.

cached_memory_image: ^1.5.0

Usage

  • Cached image from Base64 and Display
Padding(
  padding: const EdgeInsets.all(8.0),
  child: CachedMemoryImage(
    uniqueKey: 'app://image/1',
    base64: 'iVBORw0KGgoAAAANSUhEUgAAAk0AAAFwCAYAAACl9k...',
  ),
)
  • Cached image from Uint8List and Display
Padding(
  padding: const EdgeInsets.all(8.0),
  child: CachedMemoryImage(
    uniqueKey: 'app://image/1',
    bytes: Uint8List.fromList([1,2,3,4,5]),
  ),
)

How it works

The cached memory images stores and retrieves files using the flutter_cache_manager.
