Since I spend more and more time in cursor, I ported my personal editor theme (Sweet Pascal) from IntelliJ to VScode.
The pastel colors are inspired by Sweet Sweet Canyon from Mario Kart 8

I now have to fix @wiredash.com. Moving to the next page is impossible. The animation is taking ~10min to settle (vs 500ms previously)
I hope I find a clever way to distinguish between the new and old Flutter SDK

Only for macos. On linux and windows you get way more disk space.

Using the pubspec.lock is not enough. Also the flutter version needs to be locked.
When the flutter version changes, its locked dependencies change. This forces pub get to find new compatible packages.
This updates some packages regardless of what is defined in the lockfile.

I invested a full day testing cursor.com. I haven't written a single line of code. It was all generated and good 🤯
I was especially amazed by refactorings across the codebase. Faster than me ⚡️
The actual workflow is like reviewing PRs. Suggest a change, review the change. Iterate, land the change.

Making progress. The spot timeline now supports hot-restart for spot developers. This makes it way easier to work with Jaspr
It takes Dart ~1.5s to compile the app to JS.
