content_disposition

Cross-platform (web, mobile, desktop) parser for the HTTP Content-Disposition header. Pure Dart — no dart:io — so it works the same in a browser and on native targets.

Implements the practical subset of RFC 6266: the disposition type and the filename / filename* parameters. filename* (RFC 5987 extended notation, e.g. UTF-8''fa%C3%A7ura.pdf) is decoded and takes precedence over a plain filename.

Usage

import 'package:content_disposition/content_disposition.dart';

final name = ContentDisposition.filenameOf('attachment; filename="danfse.pdf"');
// -> 'danfse.pdf'

final cd = ContentDisposition.parse("attachment; filename*=UTF-8''fa%C3%A7ura.pdf")!;
cd.type;     // 'attachment'
cd.filename; // 'façura.pdf'
