I'm curious about the min window size allowed in iPadOS 26's multi-window system. Some of my apps are responsive and look good at 100x100, but likely overflow at 50x50.

I'm still on Flutter 3.24.5, which I believe was the last truely stable version. When will critical bugs in 3.27 and 3.29 be fixed? Even then, these versions won't receive backports, so for me, they'll essentially remain untouched forever. E.g. github.com/flutter/flut... github.com/flutter/flut...

Finally solved the Go dependency issue I'd been battling in IntelliJ IDEA for months. It turns out a permission error related to the env file in GOROOT – which should have been a file – had somehow been replaced with a directory of the same name. So bizarre!

I struggled a bit to find out how to scroll to an element smoothly with scrollIntoView() in a website made with Jaspr. Its argument needs to be JSAny, but js_interop doesn't (apparently) have a method to convert a Dart Map to JSObject. Evetually turned out jsify() was the one.

Considered Turso and skipped it recently, but wanna think about using it in the future. I guess it is now one of the most affordable cloud relational database services. Only $4.99 (or 5.99) /month for 1,000 databases and 2.5 billion monthly rows read. turso.tech/blog/turso-c...

Scrolling obviously stutters in my app. Seems the cost of creating widgets is higher than the benefit of lazy creation in SliverList. Using Column makes it smoother, but the initial build is probably more costly. I wonder whether to fix the cause now. It isn't that noticeable in profile mode.

I had been a little skeptical that running a lot of queries consecutively wouldn't be a problem in SQLite (and actually haven't measured the performance), but found the document had a dedicated page about it. It says even N+1 Queries are fine. www.sqlite.org/np1queryprob...

Asked an AI about things to be cautious about when using the WAL mode in SQLite on a mobile app. I didn't know WAL might not work on an SD card. I'm lucky I'm using Drift for DB operations but also using sqflite's getDatabasesPath() together to get `data/data/xxxx/databases/`, which isn't in SD.

So Turso will allow us to create up to 500 databases with 1-day PITR and no cold starts for free, or with 10-day PITR, 3-day audit logs and no archiving for only $4.99 (down from $9). Sounds very affordable and nice! turso.tech/blog/upcomin...

I saw this post just the right time when I was struggling to access ‛window.navigator.language‛ using package:web on a static site created with Jaspr, only to get an incompatibily error. The universal_web package (used together with kIsWeb) solved the issue.

Started to migrate my developer website from Svelte to Jaspr. The experience is much better than when I created part of my blog site with it 2.5 years ago. It's impressive that even styling is possible via Dart, which was not possible before IIRC.

Drift stores a date and time as an epoch time in seconds by default. To change the precision to milliseconds, it is necessary to either (a) use IntColumn + a converter instead of DateTimeColumn, or (b) configure to store DateTime as a string. Both have pitfalls. Wish it was easier.

Topics of a package seem to affect the order of search results on pub.dev. I recently added "rich-text", "link" and some more topics to one of my packages, which had had only "text" before. A search by "rich text" or "link" now shows the package in the first or second page.

IntrinsicHeight sometimes doesn't align the height of children of a Row (dunno why). CustomMultiChildLayout is another option, but cannot be used if the Row height is unbounded. So I created a custom RenderFlex as a last resort. IMO, this should be possible out of the box in #FlutterDev.

Well I'll be reverting that change. When using workspaces all of the workspaces in the project seem to be bundled with the app, even if not referenced by the app pubspec. Surely that's a bug.

TIL: Everything is flipped in RTL (or at least in Persian), more thoroughly than I thought. Even the question mark is not an exception. It feels to me as if they live in a mirror. How interesting!

Flutter automatically flips (most of) the UI horizontally including icons in RTL locales. But is this really correct?

Keeping a tooltip open is possible with TooltipTriggerMode.manual + GestureDetector + TooltipState.ensureTooltipVisible() in Flutter, but a tap on the Tooltip child reopens the tooltip instead of closing it. As a workaround, I had to use Tooltip.dismissAllToolTips() to get the visibility status.

The visibility status (_visible) of a tooltip is private. As a workaround, I had to use Tooltip.dismissAllTooltips() to get the status. The method is actually not for getting the status, so using it is a bit hacky. The API of the Tooltip widget is weird IMO.

It's kind of fun to try opening mobile apps offline and see what happens. X and Mastodon show cached data, and oh, BlueSky... I don't think all kinds of apps should support offline use, but it's definitely bad that an app surprises already logged in users by showing the login page.

Wondering why the current state getter added to go_router several weeks ago returns a nullable type. Neither currentConfiguration, last or buildState() is nullable.

I didn't know this either. That's easier than what I usually did, like running "flutter build web" and then starting a server with dhttpd.

Is enableFeedback existing in various widgets really working? For example, it is enabled by default in InkWell, but I've never seen it behave as the property name implies. There's no feedback on any of my Android phones. Does it require any special setting?

This would be much longer code if the language doesn't have pattern matching, collection-for/if and the spread operator. Dart is so powerful these days.

It was not as hard as I was thinking to implement a feature to swipe down to close an image, which can also be zoomed and panned. It was achieved with only a little over 100 LOC. One of the things I think is nice is a movement by a pull is slowed down if the distance is enough to close the view.

ListView automatically avoids its scroll ends covering outside the safe area, while other scrollable widgets (probably) don't. It's a bit confusing in an app that supports edge-to-edge. I have to decide whether to add a bottom padding manually depending on the widget.

JsonCodable has just appeared in Dart and it is still experimental, so why don't we take this opportunity to change the naming convention of conversions between an object and a map? fromMap/toMap would be more appropriate than fromJson/toJson.

While the disabled colour of NavigationBar is configureable, that of NavigationRail is always onSurface.withOpacity(0.38). And when a widget doesn't have the configuration, I expect ThemeData.disabledColor to be used, but that's not the case. Why is Flutter so inconsistent?

000

Kabo @kaboc.bsky.social · 13/04/2024

I was wondering for a while how to convert a translucent colour to an identical-looking opaque colour in Dart, and then suddenly realised it was just a matter of using Color.alphaBrend. Would be handy to have a wrapper method that works appropriately with both light and dark modes.

Inside onPopInvoked - pop() should be called only when false is passed in, otherwise it leads to a strange behaviour (at least on Android emulator on my PC) - maybePop() causes an infinate loop

000

Kabo @kaboc.bsky.social · 27/02/2024

Without onPopInvoked - Cannot go back unless pop() is used - maybePop() does nothing (note: back button in AppBar uses maybePop) With onPopInvoked - pop() navigates back and calls onPopInvoked with `true` - maybePop() calls onPopInvoked with `false` without navigating

PopScope is confusing. Here is a note for future reference (only for use with Navigator API) Back gesture - iOS: Gesture itself is disabled, so onPopInvoked is not called - Android: onPopInvoked is called with false, but not when gesture is cancelled api.flutter.dev/flutter/widg...
