Something to try:

• Aida/Web: https://www.aidaweb.si/tutorial
• Seaside: https://www.seaside.st/documentation/tutorials
• Book: https://book.seaside.st/book 
• Pharo-by-example is a hijacked web site, just ignore it.

The critical question is why bother? Flutter / React already offer well-rounded frameworks, and Smalltalk is just yet-another-esoteric language. It’s on the same level as JS/TS/Dart when it comes to “stuff I only use occasionally”, with the typical issue of feeling mostly write-only.

On that part, I ended up actually enjoying Dart as it seemed like a suitable compromise between Java, JS, and TS.

Flutter vs ReactJS:

• Pro of Flutter = dev in IJ… The integration is excellent.
• Cons of Flutter = dev in IJ… Requires IJ to edit a project.
• Same goes for ReactJS. The VS Code integration is good, but lacks an IJ-level project management.
• VS Code is good for short-sided projects (e.g. Wazz), whereas IJ is better for large project organization.
