@xiaowei-guan |
1.Fix spelling issues. 2.Do not need to destroy swapchain image when destory the renderer. 3.Replace memset with zero-init. 4.Free command buffer when begin command buffer or end command buffer failed. 5.Fix return wrong api version issue.

The problem was solved with the help of @swift-kim. |

@JSUYA Yes, if we want to run vulkan app on RPI4, we need to install vulkan related rpm files. @swift-kim @JSUYA Thank you, the issue has been fixed. |

@JSUYA Can you review the code? |

@xiaowei-guan On TV, it failed to create a vk instance. And since libvulkan is not included in the binary by default, merging vulkan PRs for the embedder and engine will prevent Flutter apps from running in the basic Common Headed Profile. |

Question
External texture is not supported?

There was a problem hiding this comment.
I have finished code of External texture:
- Engine PR : [Tizen] Support render texture for vulkan + impeller flutter#17
- Embedder code : xiaowei-guan@6a94746
After vulkan backend PR released, I will create a new PR for texture.

In tizen repo, the vulkan so files are uploaded, but they are not actually included in the image binary. Therefore, unless user install the RPI binary and separately install libvulkan, user cannot run a Flutter app even if they do not use the EVulkan renderer. How about additionally releasing libflutter_tizen.so that supports the Vulkan renderer? For example... The flutter-tizen tool can download experimental artifacts to the cache and load experimental SO files using predefined settings or separate flags. (Ex flutter-tizen run --dart-define=USE_FLUTTER_TIZEN_EXPERIMENTAL ?) please suggest better approaches if you have them. |
result is VK_SUBOPTIMAL_KHR or VK_ERROR_OUT_OF_DATE_KHR.

Because vulkan libs are not included in the binary by default. we need to install vulkan libs before run vulkan app on device.
How to set vulkan for Tizen device:
RPI4 hreaded image already has vulkan driver, no need to install to the target.
For TV image, you need to install vulkan driver manually to the target.
vulkan-loader
vulkan-tools
vulkan-wsi-layer
rpm -Uvh --force --nodeps *.rpm
vulkaninfo or vkcube
I can run vulkan backend app on RPI4.
Because the vulkan driver on TV is not stable, I can only run vulkan backend app on Tizen 8.0 with old version dirver.
