Planned Material Library Features Jul-Sept 2019 #35088
Description
This issue represented material library work we'd planned to undertake from July-September 2019. It has been replaced by a new similar issue that covers October-December 2019. If you're interested in voting or commenting on our latest plans please review #43035.
During the period covered by this issue we accomplished a subset of what we'd hoped to do. Here's a summary; see below for details.
- Support for dark mode per the latest Material spec.
- New ToggleButtons widget.
- Exposed Android 10's system "gesture insets".
Over the same three months we landed 113 pull requests and closed 146 issues. Most of the issues, and some of the pull requests were provided by developers outside of the Flutter team within Google. We thank you-all for that!
Features for which the work is now relatively complete are marked with ✔️.
There's a similar list of Cupertino library features, see #35026.
✔️ Dark Mode
Existing support to be updated per the latest Material spec.
- Updated ColorScheme.dark(), #36106.
- Material widget's color now changes per elevation in dark mode, #35560.
- SnackBar dark mode updates, #37038.
- Added ThemeData.from(): Construct a Theme from a ColorScheme, #37355.
- Added MaterialApp.themeMode to sync the app with the system dark mode setting, #35499, #36399.
Updated Date Picker
An improved UI that handles small screens better and supports selecting date intervals.
- Improve small screen layout, #31514.
- Increase TimePicker touch targets, #32053.
- TimePicker moves to minute mode after hour selection, #31566.
Search Bar
Support for "persistent search" per the Material spec. There's an existing issue for this.
✔️ Toggle Button
Also called a "Segmented Control". Defined in the Material spec.
- Added ToggleButtons widget, #34599.
- Added ToggleButtons.textStyle, #38813.
- ToggleButtons testing and docs, #38898, #38635.
- - Toggle button minimum size constraints, #39857.
Reorderable List Animation
Improved interaction drag and drop animation, support for animating insert and remove.
Android Q Navigation
Android Q can reserve swipe gestures that are initiated from the edges of the screen for system navigation. Apps will need to be aware of the system's "gesture insets" and the Scaffold drawer will have to accommodate them.
An overview of the work planned for Android Q (now "Android 10") is here: Android 10 / Android Q Issues and Features.
- Add MediaQuery.systemGestureInsets to support Android Q, #37416.
- (Engine) systemGestureInsets, engine/10413.
- (Engine) systemGestureExclusionRects, engine/11441, engine/11451.

maybe create a listview that has a feature of enabling the user to select multiple items inside it and give the developer the freedom to implement the actions to manipulate the selected items

Calendar controls would be the hardest for me to get right, the rest I could hack together and feel like it would work, but a top notch calendar (would love a good time picker to work with it) would be awesome

We have built a date picker with almost the exact functionality shown here, using some code from the current date picker (but turning it into a vertically scrolling and interval supporting version). However, achieving good performance with that widget is rather hard, so we would welcome an official version.
That said, I feel the priority should be on Android Q navigation since it's quite obviously vital to have that working.

There is some jitter in Flutter ListView scrolling, and the scrolling speed is a little slow. It is hoped that it will be further optimized.

The built in search widgets are just down right awful! Everything is hard-coded, plus I've never seen an app actually use a search page that looked like that. The Persistent Search is VERY needed.
Waffulz commentedon Jul 12, 2019
This is hard though. Im between date picker, toggle button and search bar.
mdrideout commentedon Jul 12, 2019
Date picker please!
codinesh commentedon Jul 12, 2019
Dark mode and date picker please.
kolmakovruslan commentedon Jul 12, 2019
Calendar, search bar

I think you missed one of the most important widgets which play a crucial role in user-friendliness, which is 'Feature discovery'.

Search Bar & Toggle Button
amugofjava commentedon Jul 12, 2019
Search Bar gets my vote. This is such a common widget in apps this would be extremely useful and time saving.
amrfarid140 commentedon Jul 12, 2019
Reorderable List Animation and date picker are the most needed ones for me.

Search bar and then Dark mode!!! 😋
orestesgaolin commentedon Jul 12, 2019
In our apps there was always a discussion about proper date picker so I would love to see a good quality and versatile date picker from Flutter team.
Search and dark mode with system support would be also important to me.

jffiorillo commentedon Aug 24, 2019
