I've added a Focus.withExternalFocusNode constructor to the Focus widget (and the FocusScope widget) that makes it explicit that the widget's attributes won't affect the settings of the given focus node. This is to help address #83023, which is a snag in the API that people run into occasionally. This should help make it explicit when you want the widget attributes to take precedence, and when you don't.

This updates the onKey handler of the FocusNode that the Focus widget manages when the widget is updated and the handler has changed. Also added a setter for onKey to the FocusNode.

This removes the nullOk parameter from Focus.of, FocusTraversalOrder.of and FocusTraversalGroup.of, and creates maybeOf equivalents for each. The of methods now return non-nullable values, and the maybeOf equivalents return nullable values.

This changes FocusNode.descendantsAreFocusable so that it doesn't allow the enclosing scope to re-focus a node that is a descendant of the node with descendantsAreFocusable set to false. Because of the order in which the internal state for descendantsAreFocusable was being set, setting it to false was causing a sibling node to be focused when descendantsAreFocusable of the parent was set to false, even though it shouldn't have been focusable, because the enclosing scope would search for a candidate to be focused before the internal state was set to false. Instead of looping over the children and telling them all to unfocus (and select the previously focused node), this unfocuses the node that has descendantsAreFocusable set to false, with the disposition UnfocusDisposition.previouslyFocusedChild, so that its enclosing scope will look for a previously focused child that isn't part of the subtree being excluded. This affects how the ExcludeFocus widget behaves when turning on exclude.

This adds an ExcludeFocus widget that prevents widgets in a subtree from having or obtaining focus. It also adds the ability for a FocusNode to conditionally prevent its children from being focusable when it isn't focusable (i.e. when canRequestFocus is false). It does this by adding an descendantsAreFocusable attribute to the FocusNode, which, when false, prevents the descendants of the node from being focusable (and removes focus from them if they are currently focused).

When Focus.unfocus is called, the caller usually just thinks about wanting to remove focus from the node, but really, unfocus is a request to automatically pass the focus to another (hopefully useful) node. This PR removes the focusPrevious flag from unfocus, and replaces it with a disposition enum that indicates where the focus should go from here. The other value of the UnfocusDisposition enum is UnfocusDisposition.scope. UnfocusDisposition.previouslyFocusedChild is closest to what focusPrevious used to do: focus the nearest enclosing scope and use its focusedChild field to walk down the tree, finding the leaf focusedChild. This PR modifies it slightly so that it walks up to the nearest focusable enclosing scope before trying to focus the children. This change addresses #48903 A new mode: UnfocusDisposition.scope will focus the nearest focusable enclosing scope of this node without trying to use the FocusScopeNode.focusedChild value to descend to the leaf focused child. This is useful as a default for both text field finalization and for what happens when canRequestFocus is set to false. It allows the scope to stay focused so that nextFocus/previousFocus still work as expected, but removes the focus from primary focus. In addition to those changes, unfocus called on a FocuScope that wasn't the primary focus used to unfocus the primary focus instead. I removed that behavior, since it was buggy: if the primary focus was inside of a child scope, and you called unfocus on the parent scope, then the child scope could have focused another of its children instead, leaving the scope that you called unfocus on with hasFocus returning true still. If you want to remove the focus from the primary focus instead of the scope, that's easy enough to do: just call primaryFocus.unfocus(). Fixes #48903

This re-lands #49235 with the addition of includeSemantics flag on the Focus widget so that the FocusTraversalGroup can create a Focus widget without affecting the semantics tree. The FocusTraversalGroup uses the Focus widget to create a grouping of descendants for traversal, but doesn't actually participate in focus (canRequestFocus is always false), so we don't want it to add a Semantics widget in that case, since that can cause semantics changes. The canRequestFocus attribute can also be used when a widget is disabled, so we do sometimes want to include Semantics even if that is false, but not in the case where it is always false, as for FocusTraversalGroup. - Added a test to make sure that FocusTraversalGroup doesn't add any semantics information.

This change adds a way to provide explicit focus order for a part of the widget tree. It adds FocusTraversalPolicyGroup, which in many ways is similar to DefaultFocusTraversal, except that it groups a widget subtree together so that those nodes are traversed as a group. DefaultFocusTraversal doesn't work as one would expect: If there is more than one DefaultFocusTraversal inside of a focus scope, the policy can change depending on which node was asked to move "next", which can cause unexpected behavior. The new grouping mechanism doesn't have that problem. I deprecate DefaultFocusTraversal in this PR. It also adds OrderedFocusTraversalPolicy, which is a policy that can be supplied to FocusTraversalPolicyGroup to set the policy for a sub-tree. It looks for FocusTraversalOrder inherited widgets, which use a FocusOrder to do the sorting. FocusOrder has two subclasses: NumericalFocusOrder (which sorts based on a double), and LexicalFocusOrder, which sorts based on a String. As part of doing this, I refactored the way FocusTraversalPolicy is implemented so that it has more default implementation methods, and exposes a new protected member: sortDescendants, which makes it easier for developers to make their own policy subclasses: they only need to implement sortDescendants to get a new ordering behavior, but can also still override any of the default implementation behaviors if they need different behavior. I was able to do this without breaking the API (AFAICT).

This changes the behavior of requestFocus when it is called on a FocusNode that does not yet have a parent, so that it defers requesting focus until it receives a parent. Before this change, calling requestFocus before it had a parent was a no-op. This allows scenarios where a widget is newly added and wishes to immediately request the focus. Previously, it was very hard to make that work because requesting focus before the widget's focus node had a parent was ignored, so the developer had to wait until two frames later to request focus (one for the widget's node to be added to the focus tree, and one to request the focus). Now, in order to have a widget be focused when initially added, you just need to call requestFocus on its node when you create it, and as soon as it is added, it will automatically request focus. This is different from the autofocus attribute on the Focus widget, because it unconditionally requests focus when added (autofocus will only request focus if nothing else in the scope has focus).

This fixes an issue where lines like this: focusNode.canRequestFocus = widget.canRequestFocus ?? focusNode.canRequestFocus; Were causing the canRequestFocus bit to copy the status of the enclosing scope, since canRequestFocus also looks to the enclosing scope to decide if it can focus.

This fixes some minor things I noticed while doing another change. - Uncomments an old test that wants to be run, but can't be, and marked it as "skipped", so that the code won't rot anymore. - Added the focus state to the short string version of a FocusNode - Added a missing piece of information to findAncestorWidgetOfExactType

* Update project.pbxproj files to say Flutter rather than Chromium Also, the templates now have an empty organization so that we don't cause people to give their apps a Flutter copyright. * Update the copyright notice checker to require a standard notice on all files * Update copyrights on Dart files. (This was a mechanical commit.) * Fix weird license headers on Dart files that deviate from our conventions; relicense Shrine. Some were already marked "The Flutter Authors", not clear why. Their dates have been normalized. Some were missing the blank line after the license. Some were randomly different in trivial ways for no apparent reason (e.g. missing the trailing period). * Clean up the copyrights in non-Dart files. (Manual edits.) Also, make sure templates don't have copyrights. * Fix some more ORGANIZATIONNAMEs

This adds accessors for WidgetsBinding.instance.focusManager and WidgetsBinding.instance.focusManager.primaryFocus so that they can be more easily found in IDEs and accessed. This adds a top level getter for WidgetsBinding.instance.focusManager.primaryFocus called primaryFocus, and a static accessor FocusManager.instance that returns WidgetsBinding.instance.focusManager.

This optimizes certain paths in the FocusManager, FocusNode, and FocusScopeNode classes in order to fix a regression in stock_animation_open_first_frame_average when I added more focus nodes to the tree to do focus traversal. Mainly I removed some remaining sync* iterators, and also started caching the computation of descendants and ancestors, since those are iterated over fairly often. This improves stock_animation_open_first_frame_average by about 2.8% overall (so about half of a 4.9% regression, both averaged over 10 runs). Addresses #42564

This fixes a problem with reparenting of focus nodes where it would remove the node from the scope's focused children when reparented, even if it was being reparented to another place under the same scope. This only occurred if the scope in question didn't have focus. This caused nodes to not get autofocused when they were a child of another node within the scope, and were reparented, and then the scope was given focus (as when a route is pushed). This keeps the node in the scope's child list where it was if the node is reparented under a parent within the same scope. - Added a test that tries to autofocus a TextField when the route is pushed and there is another FocusNode above the text field. This was how this was first noticed: the autofocus got ignored in this configuration. - Added a test to focus_manager_test that tests for the specific case of reparenting a node when it's in the focused children of the scope.
