HttpBody<T> class

Represents an HTTP entity, consisting of optional headers and an optional body.

This class is a generic container for HTTP request or response data. It allows storage of headers (HttpHeaders) and a typed body (T), providing convenient accessors and equality comparison via EqualsAndHashCode.

Features

• Stores optional HTTP headers.
• Stores an optional body of generic type T.
• Equality and hash code are based on headers and body.
• Immutable design for thread safety and predictable behavior.

Type Parameters

• T: The type of the body content. Use void when no body is expected.

Example

final entity = HttpBody<String>(
  'Hello, world!',
  HttpHeaders()
    ..set('Content-Type', 'text/plain')
);

print(entity.getBody()); // 'Hello, world!'
print(entity.getHeaders()?.value('Content-Type')); // 'text/plain'

Notes

• _headers may be null if not provided.
• _body may be null if not provided.
• Designed to be immutable after construction.
