Investigate ways to reduce .js bundle size on web

Package

google_fonts

Existing issue?

• [X] I checked the existing issues

What happened?

google_fonts library JavaScript itself has the file size of 8Mb. It is only library JavaScript, so fonts are loaded additionally and have their own file sizes.

Might be nice to reduce the library JavaScript file size to something acceptable for the web.

I am interested in that topic as well to bring down the bundle size for web. Is HTTP fetching at runtime enabled by default for Flutter Web? If that were the case it would at least not be a blocking call

Why is file size a concern for local, debug-mode development?

However, this does bring up the concern for release mode, where a minimal app has a main.dart.js with an uncompressed 4.1MB size, up from 1.7MB.

Is HTTP fetching at runtime enabled by default for Flutter Web? HTTP fetching is the default, and can be turned off with https://pub.dev/documentation/google_fonts/latest/google_fonts/GoogleFonts/config.html
