Material You (or Material 3)
At Google I/O this year, Google not only took the opportunity to present Android 12, but also a new version of its Material graphics library  . In this new iteration , the idea is to put the user at the center by customizing the interface according to the his/her desktop's background.
Flutter: a good pupil
Historically, Flutter has always been one of the first frameworks to implement new features in the most complete way possible. Material You was no exception to the rule, because just a few hours after the announcements, the first Widgets showed up.
Yes, but…
Flutter now supports Material versions 1 and 2 in a transparent way. How to make the transition to version 3? This is a question that is being debated on GitHub , since an "enable v3" attribute, or even a migration to the null-safety proves to be complicated to implement, due to the fact that many sizes have evolved and that the risk of "breaking" existing applications is high. As it is, the Googler Hixie proposes  to make Material 3 available as a dependency, to avoid any problem. To be continued! |

Foldable smartphones hype:
Microsoft Surface Duo, Samsung Galaxy ZellersMicrosoft Surface Duo, Samsung Galaxy Z Flip/Fold…, phones with foldable screens are multiplying, but user experience optimization depends largely on manufacturers' efforts. Google will therefore release a 12L version (also named Sv2) to fix the problem and standardize the interface. The public version will be released in Q1 2022 (together with a Pixel Fold?).
Letterbox mode
This version mainly modifies the Android graphical aspect, because the APIs (multi-window, tablet mode…) already exist. Nevertheless, if your application only offers a smartphone version, it will switch to letterbox mode. In practical terms today, the application tries to fill the whole screen, whereas with this mode, it will appear in smartphone format. It will still be better than today, anyway.
But also
Looking at differences in APIs , we note the addition of a class dedicated to sound spatialization or then again changes for the VoiceInteractionSession. |

Tizen, Samsung's operating system
Samsung phones use Android as their operating system. For the rest of its ecosystem (including its televisions or connected watches), the Korean giant has opted for Tizen. The system seems to have a fair amount of stability, despite a rather meager application store in terms of content.
A partnership with Google
In May 2021, Samsung announced it would return to Wear OS (an Android-based operating system) for its connected watches. Tizen's future seemed to be gathering dust at the time, but a Git was simultaneaously made available , to allow the development of Flutter applications for Tizen. Out of the blue, regular commits have been released since then.
Tizen opens to other manufacturers
At its developer conference , Samsung announced it wants to expand its reach by allowing à other manufacturers to use Tizen (although it has not given any names yet). This is great news for us Flutter developers, as we will not only be able to develop applications for Android TV, but also for Tizen! |
