Previously the engine would load all embedded fonts listed in the app's
font manifest during startup. This change creates a Skia font manager that
is backed by the engine's AssetManager and can load embedded font assets
on demand.
* Reland "Added IsolateNameServer functionality (#5410)"
This reverts commit 1598c7ad7b830b298647c17a0c85f3648f6b737d.
* Fixed issue with isolate_name_server_test which caused test to timeout
* Disabled thread_annotations on Android as they aren't supported in the
NDK headers for std::mutex. Readded thread annotations to
IsolateNameServer.
* Added IsolateNameServer functionality, which allows for the association
of string names with isolate SendPort ids that can be used to establish
inter-isolate communications.
On a Linux host, we were having to convert the type of the bitmap to N32, but we weren't also fixing the channel order to RGBA, so consequently we were getting BGRA when the API was asking for RGBA. This forces the color format to be RGBA when that is what is asked for.
We weren't needing to do conversion on macOS, so macOS was always getting RGBA.
This updates the documentation for StrokeJoin and StrokeCap to contain animated diagrams that describe their function. The actual diagrams reside in the assets-for-api-docs repo.
* Roll Dart to 011676641a8b4b77bb372384c712709cbf037675.
Reverts cb86a973a7c96bddf304f611b963064133a5cc8c and uses Dart_NewExternalTypedDataWithFinalizer.
* update license goldens
* Enable sweep gradients
* Use _matrix4IsValid
* Add assert for startAngle < endAngle
* Use radians for startAngle and endAngle
* Update AUTHORS
* Better assert on matrix4IsValid
This is helpful for some Material Design widgets, which are specified as a semi-transparent color over top of a "material". In some cases, the resulting alpha-blended color can be used instead of compositing an additional shape with an opacity.
This new Color.alphaBlend function mimics the alpha blending function, and creates the resulting combined color. The optimization only works for solid color shapes that have the same geometry, of course.
PlatformMessageResponseDart will wrap large responses in Dart external typed
data objects in order to avoid copying the data into a new buffer.
Previously these objects were created with the Dart_TypedData_kByteData type.
A weak persistent handle is then associated with the ByteData to provide a
finalizer that deletes the raw buffer. However, the Dart VM could call
finalizer on the ByteData even if references still existed to the Dart ByteBuffer
object backing the ByteData. The ByteBuffer would then be referencing a deleted
raw buffer.
This PR prevents that scenario by creating a Dart_TypedData_kUint8 object,
attaching the finalizer to that object, and then wrapping it in a ByteData.

Platform messages are only support in the UI isolate. Secondary isolates
do not have a window that can receive incoming messages, and outgoing messages
are not tagged with a destination isolate and thus will always be dispatched
to the UI isolate.
