| FlutterVulkanDeviceHandle FlutterVulkanRendererConfig::device |
VkDevice handle. Must not be destroyed before FlutterEngineShutdown is called.
Definition at line 968 of file embedder.h.
Referenced by InferVulkanPlatformViewCreationCallback(), and main().
| size_t FlutterVulkanRendererConfig::enabled_device_extension_count |
The number of device extensions available for enumerating in the next field.

Referenced by InferVulkanPlatformViewCreationCallback(), and main().
| const char** FlutterVulkanRendererConfig::enabled_device_extensions |
Array of enabled logical device extension names. This should match the names passed to VkDeviceCreateInfo.ppEnabledExtensionNames when the logical device was created, but any subset of enabled logical device extensions may be specified. This field is optional; nullptr may be specified. This memory is only accessed during the call to FlutterEngineInitialize. For example: VK_KHR_GET_MEMORY_REQUIREMENTS_2_EXTENSION_NAME

| FlutterVulkanInstanceProcAddressCallback FlutterVulkanRendererConfig::get_instance_proc_address_callback |
The callback invoked when resolving Vulkan function pointers. At a bare minimum this should be used to swap out any calls that operate on vkQueue's for threadsafe variants that obtain locks for their duration. The functions to swap out are "vkQueueSubmit" and "vkQueueWaitIdle". An example of how to do that can be found in the test "EmbedderTest.CanSwapOutVulkanCalls" unit-test in //shell/platform/embedder/tests/embedder_vk_unittests.cc.

| FlutterVulkanImageCallback FlutterVulkanRendererConfig::get_next_image_callback |
The callback invoked when the engine requests a VkImage from the embedder for rendering the next frame. Not used if a FlutterCompositor is supplied in FlutterProjectArgs.

| FlutterVulkanInstanceHandle FlutterVulkanRendererConfig::instance |
VkInstance handle. Must not be destroyed before FlutterEngineShutdown is called.

| FlutterVulkanPhysicalDeviceHandle FlutterVulkanRendererConfig::physical_device |
VkPhysicalDevice handle.

Referenced by InferVulkanPlatformViewCreationCallback(), and main().
| FlutterVulkanPresentCallback FlutterVulkanRendererConfig::present_image_callback |
The callback invoked when a VkImage has been written to and is ready for use by the embedder. Prior to calling this callback, the engine performs a host sync, and so the VkImage can be used in a pipeline by the embedder without any additional synchronization. Not used if a FlutterCompositor is supplied in FlutterProjectArgs.

| FlutterVulkanQueueHandle FlutterVulkanRendererConfig::queue |
VkQueue handle. The queue should not be used without protection from a mutex to make sure it is not used simultaneously with other threads. That mutex should match the one injected via the |get_instance_proc_address_callback|. There is a proposal to remove the need for the mutex at https://github.com/flutter/flutter/issues/134573.
