Usage

Basic Usage

To use hash_cached_image in your Flutter project, follow these steps:

Add the package to your pubspec.yaml file:

dependencies:
  hash_cached_image: ^1.0.0

Import the package in your Dart code:

import 'package:hash_cached_image/hash_cached_image.dart';

Use the HashCachedImage widget to display images with cached network loading and optional blur hash placeholders and error handling. Here's a basic example:
```
HashCachedImage(
  imageUrl: 'https://example.com/image.jpg',
  hash: 'LEHV6nWB2yk8pyo0adR*.7kCMdnj',
  height: 200,
  width: 200,
  placeholder: (context) => const CircularProgressIndicator(),
  errorWidget: (context, error, stackTrace) => const Icon(Icons.error),
  fit: BoxFit.cover,
)
```
In this example, replace 'https://example.com/image.jpg' with the URL of the image you want to display. The hash parameter is optional and can be used for blur hash placeholders. You can customize the placeholder and error widgets, as well as other properties like height, width, and fit to suit your UI requirements.

Global Configuration

You can set global placeholder and error widgets for your entire application:

import 'package:hash_cached_image/hash_cached_image.dart';

void main() {
  HashCachedImageGlobalParameter().setGlobalParameter(
    globalPlaceholderWidget: (context) => const CircularProgressIndicator(),
    globalErrorWidget: (context, error, stackTrace) => const Icon(Icons.error),
  );
  runApp(const MyApp());
}
