This adds a simple spacer widget first suggested by Scott Stoll (@ScottS2017) in the abandoned PR #15802
This PR replaces that one, cleans it up, and adds a test.
This fixes#17169 by adding onChangeStart and onChangeEnd to the slider. These will be called when the user starts a change, and when they end a change, regardless of whether that change is a tap or a drag.
These differ from onChanged, in that they only report when the user starts and ends an interaction, not at every slight change.
Before this change, if you specified a non-null textTheme, but the theme you specified didn't have a body2 defined, then creating a ChipTheme would assert (which means creating a ThemeData would fail).
This adds handling for this corner case to default to reasonable values in that case. The slider had the same problem, but for accentTextTheme, so I fixed that too.
While I had the patient open, Hans and I noticed that TextTheme.merge wasn't doing the right thing in the case where some members were null either, so I fixed that, and added some examples, since merge/copyWith are common operations that are not always well understood.
Fixes#17251
* Allow customization of TextSpan in EditableText
* Addressed PR comments
* Added test with custom-styled EditableText subclass
* More code style fixes
In order to avoid checking binaries into flutter/flutter,
this comparator can be used to retrieve golden files from
a sibling flutter/goldens repository.

New a11y traversal:
- sort direct sibling SemanticsNodes only
- use new sorting algorithm
- implement RTL
- test semantics in traversal order by default
- add AppBar traversal test
- breaking: remove nextNodeId/previousNodeId from the framework
- breaking: remove DebugSemanticsDumpOrder.geometricOrder
When passing a Color object with same R/G/B code ( e.g. [new Color.fromRGBO(100, 100, 100, 1.0)] ) to HSVColor.fromColor(Color color) , the hue in return will be NaN .
This adds a toImage function to RenderRepaintBoundary that returns an uncompressed raw image of the RenderRepaintBoundary and its children. A device pixel ratio different from the physical ratio may be specified for the captured image. A value of 1.0 will give an image in logical pixels.
This addresses #16593 by removing the unneeded assert in the setter for constrainedAxis. Null was meant to be allowed there.
This replaces #16599 and fixes#16593, reported by @maksimr
This chip demo is more interactive than the last one, trying to exercise all of the types of chips for a demo that lets you select different types of "chips" (like tortilla, wood, micro, etc.), and then filter them and select an action on them.
* Fine-tune iOS's scroll start feel
* remove negations in doc
* Our own dart-side gesture arena also contributes to the 'jerk'. Make sure that snap is accounted as well.
* Added more code comments from review.
This is a PR giving some love to the abandoned PR #16263 by @harrisonturton
I've added a test, and formatted it to be readable.
Currently the CircleAvatar does not set a fit property on the DecorationImage it uses to paint images. This causes non-square images to not fully cover the circle, which looks pretty bad. This PR sets it to BoxFix.cover.
Fixes#13478.
