Convert XML to Dart online, free. XML is a verbose, self-describing markup format used in SOAP, RSS and enterprise systems. Null-safe Dart classes model data for Flutter apps and Dart services. XML to Dart conversion parses your XML against the W3C XML 1.0 grammar (https://www.w3.org/TR/xml/), builds an in-memory model of its keys, nested objects and arrays, then emits ready-to-use Dart types following the Dart language tour conventions. Processing runs in your browser in JavaScript with no upload or server round-trip — no size limit beyond your device's memory, so multi-megabyte documents convert in milliseconds and sensitive payloads never leave your machine. Typical uses include Flutter mobile apps, Dart backends and JSON model classes.
It maps the full structure of your XML onto idiomatic Dart types, following the Dart language tour conventions. 100% free, no registration, and complete privacy — everything runs locally in your browser, so your data never touches a server.
Paste XML and generate Dart types from Dart immediately. Conversion runs client-side, so there is no upload wait and large documents stay fast.
Nested XML objects, tables and arrays are mapped faithfully onto Dart, including nested types and optional fields.
Your XML never leaves your device — everything is processed locally in JavaScript, with nothing logged or stored.
Unlimited conversions with no account, no quotas, and no watermark. Works on desktop and mobile.
A XML document and its Dart equivalent:
XML input:
<product>
<sku>A-100</sku>
<price>19.99</price>
<active>true</active>
</product>Output:
class Product {
final String sku;
final double price;
final bool active;
Product({required this.sku, required this.price, required this.active});
}Paste your XML into the editor and press "Convert to Dart". The tool parses it against the W3C XML 1.0 grammar, then generates Dart types following Dart language tour conventions — instantly and entirely in your browser. You can validate or format the XML first to be sure it is clean.
XML has no native numbers, booleans or arrays. Repeated child elements become lists in Dart, attributes and element text become fields, and values stay strings unless Dart coerces them — so review numeric or boolean fields after converting.
Optional or nullable members in the generated Dart are inferred from keys missing in some records of your XML, following Dart language tour. Include the optional fields in your sample so they are typed correctly.
XML (eXtensible Markup Language) (XML) — XML is a verbose, self-describing markup format used in SOAP, RSS and enterprise systems. Dart classes (Dart) — Null-safe Dart classes model data for Flutter apps and Dart services. This converter maps the structure of your XML onto Dart so you can use it for Flutter mobile apps.
Yes. Invalid XML is flagged with a clear error before anything is converted. Common XML problems to check are matched start and end tags, a single root element, and quoted attribute values. Starting from clean input keeps the generated Dart accurate.
Yes. The entire XML-to-Dart conversion runs locally in your browser in JavaScript — your XML is never uploaded, logged or stored. That matters when the data is something like SOAP web services, which should not leave your machine.
The generated Dart is ready for Flutter mobile apps, Dart backends and JSON model classes. Copy or download it and drop it straight into your codebase.
