7 things to keep in mind while building jetpack composable’s

Although the documentation for Jetpack Compose is considered to be very good, we often notice some problems only when using a specific tool. If you'd prefer to learn from someone else's rather than your own mistakes, then check out this article.

That’s all from us

As reported by several independent sources, Samsung is involved in the development of Fuschsia OS, and recent reports suggest the company is ready to ditch Android entirely and switch to the new system. Of course, such a shift would take years and the two systems would coexist for a long time. We cannot expect Samsung to take such a big risk overnight, because if Fuchsia OS does not work out, may bury the entire mobile department of the manufacturer.

The Nest Hub Max may soon be switched to Fuchsia — Google’s homegrown operating system as internal testing ramps up. Earlier this year, Google took the bold step of updating existing first-gen Nest Hub smart displays from their Linux-based Cast OS to the company’s long-in-development Fuchsia operating system.

At this point, there’s no way to know how long it will be before retail Nest Hub Max devices will be updated with Fuchsia, if at all. If things follow the pattern of the original Nest Hub, Fuchsia will be made available first to those in the Preview Program in the Google Home app.

Isolates spawned via the Isolate.spawn() API are now grouped, operate on the same managed heap and can therefore share various VM-internal data structures.

This leads to ~100x faster isolate startup latency, ~10-100x lower per-isolate base memory overhead and ~8x faster inter-isolate communication.

Dart 2.15 is now available in the flutter beta channel, more details can be found here: https://github.com/dart-lang/sdk/blob/main/CHANGELOG.md

Fuchsia OS update brings no significant changes to the Nest Hub. Since Google uses Flutter to build its smart display experience, the user experience will remain same even though the underlying OS is changing from Linux-based OS to Fuchsia OS. Google says the Fuchsia update for the Nest Hub will roll out to users over the coming months, starting from users in the Preview Program.
