Support for using dart:mirrors has been deprecated for nearly two years.
this removes support for enabling mirrors from the embedder as
documented in the deprecation comment. This was primarily added as a
workaround for an internal tooling usecase, which no longer exists.
Issue: https://github.com/flutter/flutter/issues/120924
GObject's dispose() method may be called multiple times. Guard against
trying to disconnect the same signal multiple times by clearing the ID
to avoid warnings when closing the window.
```
(bug:74019): GLib-GObject-WARNING **: 11:15:08.697: ../../../gobject/gsignal.c:2731: instance '0x55e1c3ea0200' has no handler with id '255'

This PR takes a step back and changes the GTK IM client window back from FlView to GtkApplicationWindow as it was before #33111. The window was originally changed to FlView to make the code testable by cutting a dependency to gtk_widget_translate_coordinates(). The change was hard to revert because there were several conflicting changes on top. Therefore, this PR introduces an FlTextInputViewDelegate to be able to provide coordinate mapping in a testable way.
Fixes: flutter/flutter#108832
When Orca has "Speak object under mouse" enabled, it tries to get the
text range extents for any object that implements the AtkText interface
and gets a bit confused by our AtkText stub implementation that merely
returns null for `get_text`.
Removing the stub implementation helps to avoid the issue that Orca
would try to call `atk_text_get_range_extents()` with `start_offset=0`
and `end_offset=0`:
> Atk-CRITICAL **: atk_text_get_range_extents: assertion 'start_offset >= 0 && start_offset < end_offset' failed
`gdk_keymap_get_for_display()` does not transfer ownership to the
caller. Destroying the keymap object would cause problems further down
the road when `GtkWindow` gets to clean up and tries to destroy the
same keymap.
* Make FlAccessibleNode derivable
This allows introducing specialized subclasses that implement such a11y
interfaces as AtkEditableText that should not be implemented for the
generic node.
* FlAccessibleNode: add set value, text selection & perform action
Prepare API required for the upcoming AtkEditableText implementation.
* FlViewAccessible: postpone child node creation
This changes the a11y node creation flow so that (unknown) child nodes
are not pre-created when their parent is updated but "pending" child
node IDs are collected for later. Parent-child relationships are
established at the end of update batches when all nodes have been
created.
* Add FlAccessibleTextField that implements AtkEditableText
Solves: flutter/flutter#103191
* FlEngine: add fl_engine_update_accessibility_features()
* FlSettings: add API for high-contrast & animations
* FlEngine: allow passing mock messenger at construction time
* FlSettingsPlugin: report accessibility features
Merges most (but not all) of the impeller .clang-tidy rules into the
main .clang-tidy config. Merges:
readability-identifier-naming.PrivateMemberSuffix (_)
readability-identifier-naming.EnumConstantPrefix (k)
modernize-use-default-member-init.UseAssignment
Does not merge:
readability-identifier-naming.PublicMethodCase (CamelCase)
readability-identifier-naming.PrivateMethodCase (CamelCase)
These last two are not merged due to the non-trivial number of existing
field accessors that use field_name() methods to directly return
field_name_. While these are permitted by the C++ style guide, we may
want to move to a single, simple rule and name everything in CamelCase.
These can be enabled in a followup patch.
No new tests added, since this change is style-only.
Let MockBinaryMessenger internally manage the FlBinaryMessenger wrapper
instance and provide it via operator FlBinaryMessenger*() to avoid
having to create two objects in every test. The same technique was used
for MockSettings in #32618.
This PR is a continuation of #33111 and includes necessary changes to test the `TextInputType.setClient()` platform channel call. Testing the actual text input flow requires a mock IM context that will follow in a separate PR.
* [Linux] pass GdkWindow instead of FlView to FlTextInputPlugin
* [Linux] add MockBinaryMessenger::ReceiveMessage()
* [Linux] add test for TextInputType.setClient
* Drop the offscreen window
GdkOffscreenWindow requires display & screen which is a problem in
headless mode. Luckily, we don't really need a window instance in tests
because its only passed as a client window to the IM context which will
be mocked out when we get to tests that depend on it.
GTK IM operates in [coordinates relative to its client window](https://docs.gtk.org/gtk3/method.IMContext.set_cursor_location.html#:~:text=The%20location%20is%20relative%20to%20the%20client%C2%A0window.). Let GTK
IM use the native window that backs FlView, which is the same native
window that is used for key event processing - see GDK_KEY_XXX_MASK in
fl_view_realize().
This is an important step towards testable FlTextInputPlugin because it
eliminates the depency to GtkWidget's coordinate translation API and
that way paves the road for replacing FlTextInputPlugin's FlView
instance with a plain GdkWindow. In tests, that window can be an
instance of GdkOffscreenWindow.
There are no tests included yet but after a few more refactoring steps
it will be possible to execute tests like this: [fl_text_input_plugin_test.cc](f2e0d91b59/shell/platform/linux/fl_text_input_plugin_test.cc).
The other refactoring steps are visible at [jpnurmi/engine/commits/text-input-plugin](https://github.com/jpnurmi/engine/commits/text-input-plugin).
