Installation

Add the package to your Flutter app:

dependencies:
  animated_streaming_markdown: ^0.3.7

Install dependencies:

flutter pub get

Import the public API:

import 'package:animated_streaming_markdown/animated_streaming_markdown.dart';

Requirements​

  • Flutter >=3.10.0
  • Dart SDK >=3.0.0 <4.0.0
  • Native build toolchain for your target platform

Because the package includes native parser integration, app targets need the usual platform build setup for Android, iOS, macOS, Linux, or Windows.

Flutter 3.10 is the minimum supported SDK. On newer SDKs the renderer uses nonlinear TextScaler when available; the compatibility path uses the linear textScaleFactor API on Flutter 3.10.

Web WASM Parser​

Flutter web is supported. Published package versions include the generated Tree-sitter WASM parser asset and bundle it through Flutter package assets automatically. App developers do not need to copy files, edit web/index.html, or add build scripts.

The package CI verifies that published WASM assets are up to date with the vendored Tree-sitter sources.

Then warm the parser before the first visible render:

await warmUpStreamingMarkdownParser();

Emscripten is only needed by package maintainers when rebuilding the committed WASM parser assets before publishing.

Rich selection copy is available on Web, Android, iOS, macOS, Windows, and Linux. The clipboard writer publishes both HTML and plain text; if the browser or native clipboard host rejects the rich payload, copy completes with the plain-text value instead.

LaTeX / KaTeX Math​

LaTeX math rendering uses a bundled pure-Dart/Flutter renderer derived from flutter_math_fork, with a Dart port of the KaTeX parser. Inline $...$ and \(...\) math and display $$...$$ and \[...\] math work without extra app setup.
