# cached_memory_image
[](https://pub.dartlang.org/packages/cached_memory_image)
A Flutter library to show images from the Base64, Uint8List and keep them in the cache directory.
## Features
#### Check file is exists
```dart
final cachedImageManager = CachedImageBase64Manager.instance();
await cachedImageManager?.isExists('app://image/1');
await cachedImageManager?.removeFile('app://image/1');
```
#### Cached Image from Base64
- Widget
```dart
CachedMemoryImage(
uniqueKey: 'app://image/1',
base64: 'iVBORw0KGgoAAAANSUhEUgAAAk0AAAFwCAYAAACl9k...',
),
```
- Image Provider
```dart
CachedMemoryImageProvider(
'app://image/6',
base64: 'iVBORw0KGgoAAAANSUhEUgAAAk0AAAFwCAYAAACl9k...',
)
```
#### Cached Image from Uint8List
- Widget
```dart
CachedMemoryImage(
uniqueKey: 'app://image/1',
bytes: Uint8List.fromList([1,2,3,4,5]),
)
```
- Image Provider
```dart
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.
```yaml
cached_memory_image: ^1.5.0
```
## Usage
- Cached image from Base64 and Display
```dart
Padding(
padding: const EdgeInsets.all(8.0),
child: CachedMemoryImage(
uniqueKey: 'app://image/1',
base64: 'iVBORw0KGgoAAAANSUhEUgAAAk0AAAFwCAYAAACl9k...',
),
)
```
- Cached image from Uint8List and Display
```dart
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](https://pub.dartlang.org/packages/flutter_cache_manager).
