Flutter Html
Flutter-html is a markup rendering engine and UI component library that parses static HTML strings and CSS styles into native user interface widgets for cross-platform mobile and desktop applications. Its core architecture manages media controllers, style cascade engines, markup-to-widget translation, and native platform view embedding through modular extension packages.
The library supports content styling using cascading style sheet rules, custom element rendering, data tables, mathematical equation rendering, vector graphics, and embedded frames or web browser components. It includes multimedia playback capabilities for audio and video elements with native player rendering, subtitle display, time-synchronized captions, speed control, and fullscreen system interface management.
Additional features cover UI layout and formatting tools such as multi-dimensional grid track arrangements, named area layouts, and right-to-left localization, alongside vector file precompilation utilities and visual layout debugging tools.
Features
- Native HTML Rendering Engines - Converts and displays static HTML string content as native user interface widgets within applications.
- HTML-to-Widget Tree Translators - Parses static HTML strings and CSS styles into native user interface widgets for cross-platform applications.
- Semantic Markup Extensions - Attaches custom handlers and matching rules to customize how specific HTML elements or markup nodes are processed.
- Extensible Component Architectures - Delegates specialized media types and complex markup tags to decoupled packages that plug into the core rendering pipeline.
- Mobile Native Component Libraries - Provides a library of modular components for building cross-platform application interfaces using native rendering trees.
- CSS Cascading Engines - Evaluates cascading style sheet rules to propagate typography and spacing properties down to descendant interface elements.
- CSS Selectors - Applies custom appearance rules to rendered elements using standard CSS selectors that cascade to child components.
- Custom Element Renderers - Applies custom formatting rules and extension handlers to override default presentation for specific markup tags.
- HTML-to-Native Renderers - Parses HTML strings and DOM documents directly, rendering them as native user interface components.
- Markup Formatting Engines - Translates structured document markup and mathematical expressions into formatted visual elements at runtime.
- Pure-Widget Rendering Engines - Parses and renders static HTML strings and CSS styles as native mobile and desktop user interface components.
- Rich Text Element Embedding - Embeds multimedia elements, vector graphics, math equations, and tabular data directly into application user interfaces.
- Content Styling - Applies cascading style sheet rules to customize fonts, colors, spacing, and borders of rendered markup.
- User Interaction Handling - Triggers custom callback functions when users select hyperlinks within rendered content, exposing target URLs.
- Multimedia Embeddings - Integrates audio, video, vector graphics, math equations, tables, and frames using modular extension packages.
- Media Playback Controls - Manages playback states and streaming sources for embedded audio and video elements through dedicated controllers.
- Video Playback Integrations - Transforms video markup tags into interactive media players respecting playback controls, sizing, and poster images.
- Native View Embedding - Integrates operating system components and web browsers directly into the widget tree by hosting platform views.
- Platform-Specific Implementations - Integrates platform implementation packages to target specific mobile and desktop environments.
- Equation Renderers - Parses TeX strings and mathematical markup tags, displaying them as formatted equations using typesetting engines.
- Column Spanning - Organizes tabular information into structured grids, calculating cell sizing, row spans, and column spans.
- Embedded Web Views - Displays external web pages and inline frames directly inside native application views with configurable dimensions.
- Interface Frame Embeddings - Displays external web content within inline and embedded frames by configuring dimensions and security sandboxes.
- Vector Graphics Rendering - Displays scalable vector images from inline markup, base64 data, local assets, or remote sources.
- Embedded Web Renderers - Embeds web browser components directly within the user interface to render web pages using native platform views.
