CrossCache class
A cross-platform caching utility for downloading and storing binary data (like images).
It supports various data sources:
- HTTP/HTTPS URLs
- Local file paths
- Flutter asset paths (
assets/...) - Data URIs (
data:...) - Base64 encoded strings
Uses a platform-specific Cache implementation (io.dart or html.dart)
for persistence and Dio for network requests.
Constructors
- CrossCache.new({Dio? dio, BaseOptions? options})
- Creates a CrossCache instance.
