I haven't been able to reproduce this bug consistently, but my theory is that
the ImageDecoder was being garbage collected before it called its completion
callback. This patch prevents that by keeping a reference to the image decoder
while the callback is in flight.
Fixes#801
This patch makes the level of the ToolBar configurable. I've also cleaned up
the Tab code slightly.
For some reason, there's still a hairline between the ToolBar and the TabBar.
We might need to rethink how we draw the background a bit here.
Fixes#1454
Focus.at() and company should be on Focus, not FocusState.
_notifyDescendants() was using the wrong runtimeType.
Let InheritedWidget update the descendants during build.
When you setState() during build, assert that you're not
markNeedsBuild()ing someone who isn't a descendant.
Typo in Widget.toString().
(These are changes cherry-picked from in-flight branches since they are
more independent and could be helpful even without those changes.)
- Change RouteBuilder's signature to take a single argument in which the
other fields are placed, so that we can keep iterating on those
arguments without having to break compatibility each time. Also, this
makes defining route builders much simpler (only one argument to
ignore rather than a variable number).
- Expose the next performance to RouteBuilders, since sometimes the
route itself might not be where it's used.
- Allow BuildContext to be used to walk children, just like it can for
ancestors
- Allow BuildContext to be used to get the Widget of the current
BuildContext
- Allow StatefulComponentElement to be referenced with a type
specialisation so that you don't have to cast when you know what the
type you're dealing with actually is.
This patch simplifies AnimationTiming and all the AnimatedValue base classes.
Also, make PopupMenu a stateless component because it has no state.
Fixes#1168
This patch converts drawer to using the "openDialog" pattern for managing its
state. Currently, the drawer entrance and exit animation aren't integrated with
the navigator's animation system because the drawer's animations can be stopped
and reversed, which the navigator can't yet understand. That means dismissing
the drawer via the system back button causes the drawer to be removed
instanteously.
