Overview
CachedMemoryImage is a Flutter package designed to efficiently display images from Base64 strings or Uint8List data while caching them locally. It ensures fast image loading by storing decoded images in the device's cache directory, reducing redundant processing and network requests. Ideal for apps that handle dynamic or frequently accessed images, it supports multiple platforms including Android, iOS, macOS, Windows, and Linux. The library simplifies image management with minimal setup and integrates seamlessly into existing Flutter projects.
Use cases
- Displaying base64-encoded images
