DartPad
package:dartpad is a library for building web applications that enable users
to prototype Dart and Flutter in the browser.
This package provides the functionality for running a Dart or Flutter development environment in the browser. By enabling you launch and communicate with:
- A worker, a dart2wasm compiled Web Worker featuring:
- An in-memory file system,
- The Dart LSP server,
- The Dart Development Compiler (DDC),
- A subset of
dart pubcommands for dependency resolution.
- A Sandbox, an isolated
iframecontaining bootstrap code necessary to:- Run, hot-reload and hot-restart DDC compiled Dart code, and,
- Proxy console output and unhandled exceptions out of the iframe.
To build a custom dartpad-like experience, you simply have to launch the worker, connect the language server to your editor, compile code and tell the sandbox to run said code, while presenting console output to the user.
Limitations
As of writing there are no support for:
- Build hooks,
- Flutter plugins,
- Flutter assets,
- Code generation with
build_runner.
It might be possible to support some of these features in the future.
