flutter_prerender 0.2.1

Command-line tool that prerenders a Flutter web app to static, crawlable HTML for SEO. Loads each route in headless Chrome and emits headings, links, meta, and a sitemap.

0.2.1

• Declare the diagram in pubspec.yaml so pub.dev renders it on the package page. It was already in the repository and the README, but pub.dev shows only what the screenshots: field points at.

0.2.0

• Add --robots, which writes a robots.txt declaring the generated sitemap. The tool produced a sitemap.xml that nothing pointed at; the Sitemap: directive is the documented way to announce one and is what webmaster tools and non-Google crawlers read. The line is only written when a sitemap was actually produced, so a crawler is never sent to a URL that would 404.
• The flag is off by default and never replaces an existing robots.txt. A project that ships web/robots.txt has it copied into the build, and silently overwriting crawl rules somebody wrote on purpose would be a worse bug than not writing the file; the existing one is left alone and the run reports it as a warning.
• Fix dart analyze reporting dozens of errors on a clean checkout. The example is a Flutter app, so the package's pure-Dart analyzer could not resolve any widget in it and called every one undefined. It is excluded from the package's analysis and still checked on its own terms with cd example && flutter analyze.

0.1.2

• Docs: make clear up front that this is a command-line tool you run against a flutter build web output, not a package you add to an app's dependencies. Also clarifies why pub.dev lists the platforms the tool runs on (Linux, macOS, Windows) rather than web.

0.1.1

• Docs: tightened the README wording and visuals.

Changelog

0.1.0

Initial release.

• CLI (flutter_prerender) that prerenders a flutter build web output to static, crawlable HTML, one file per route.
• Recovers headings, paragraphs, links and image alt text from Flutter's accessibility tree without changing app source.
• Injects <title>, meta description, canonical, Open Graph, Twitter Card and optional JSON-LD per route.
• Generates sitemap.xml.
• Parity guard that compares the generated HTML against Flutter's own accessibility text and warns (or fails, with --fail-on-parity) on injected content.
• Warnings for routes that recover no content (--fail-on-empty to make it fatal) and for routes that duplicate another route's content.
• YAML config file and command-line flags, with flags overriding the file. Invalid numeric flags are rejected instead of silently ignored.
