10/14/2019, 7:53 AMIs this to flatten views? Or are there any other reasons behind the development of such layout?

10/14/2019, 10:19 AMIt's because there are cases where using constraints is more practical, especially if you one day migrate from

10/14/2019, 10:20 AMConstraint imho completely destroy the idea of a UI tree, you end up having a parent with tons of children and no hierarchy 🙂

10/14/2019, 11:45 AMCompletely? I don't think so! Also, use the right tool for the job.

10/14/2019, 12:20 PMWell, having a constraint layout allows you to have all the view as siblings 🙂

10/14/2019, 1:51 PMIt's a question of how you're expressing your layouts and code, not just the final tree shape. But since Compose emits nodes of the layout tree independent of the composable function call tree you can still introduce intermediate abstractions where it makes sense

10/14/2019, 1:52 PMConstraintLayout plays very nicely with the visual layout editor as well for more complex arrangements

10/14/2019, 1:58 PMWill there be a visual layout editor as well working with

10/14/2019, 2:35 PMyou mean something like Android Studio has had since ConstraintLayout first released? 😄
Adam Powell
10/14/2019, 2:35 PMThe Android Studio layout editor is the product, ConstraintLayout is the implementation detail
Adam Powell
10/14/2019, 2:36 PMthe ConstraintLayout setup is a pretty good basis for building those kinds of tools

Luca Nicoletti
10/14/2019, 2:36 PMNo, I mean visually seeing edits from Jetpack Compose code to a visual editor and viceversa

10/14/2019, 2:37 PMWe've got a lot of ideas, but I'll let the part of the team directly working on those things talk more about them if they're ready to 🙂

10/14/2019, 3:19 PMI use ConstraintLayout without the layout editor, it's a "product" too.
I got a bunch of extensions that cut a lot of verbosity and enable more reuse despite the flat hierarchy.

10/15/2019, 9:17 AMvisual layout editor never worked in complex cases 😄.
Do we still have plans for instant update on emulator/device? just like the experience with flutter? I think that would be a way bigger impact than keeping alive the visual editor and lot of people are looking forward to it

10/15/2019, 9:19 AMI am interested to see constraint layout but I am surprised at the same time for the same reasons above. 🙂
Guess it will be all about the api design.
