Top Flutter HTML, CSS and SASS packages
Last updated: May 18, 2026
Rendering raw HTML and CSS within a native Flutter app is necessary when displaying rich content from a legacy CMS, email bodies, or marketing websites.
Best Practices for HTML
- Native vs. WebView: If the HTML is static text and images (like an article), use an HTML parsing package to convert the tags into native Flutter widgets (
RichText,Image). This is much faster and uses less memory than embedding a fullWebView. - Sanitization: If rendering user-generated HTML, you must sanitize it locally or on your backend to remove
<script>tags and maliciousiframeembeds to protect against Cross-Site Scripting (XSS). - CSS Limitations: Native HTML-to-Flutter parsers do not support complex CSS rules (like Flexbox, Grid, or absolute positioning). If the layout relies heavily on advanced CSS, a
WebViewis your only viable option.
