It looks like this pull request may not have tests. Please make sure to add tests or get an explicit test exemption before merging. If you are not sure if you need tests, consider this rule of thumb: the purpose of a test is to make sure someone doesn't accidentally revert the fix. Ask yourself, is there anything in your PR that you feel it is important we not accidentally revert back to how it was before your fix? Reviewers: Read the Tree Hygiene page and make sure this patch meets those guidelines before LGTMing. If you believe this PR qualifies for a test exemption, contact "@test-exemption-reviewer" in the #hackers channel in Discord (don't just cc them here, they won't see it!). The test exemption team is a small volunteer group, so all reviewers should feel empowered to ask for tests, without delegating that responsibility entirely to the test exemption group. |

Code Review
This pull request updates CapabilitiesVK::GetEnabledDeviceFeatures in capabilities_vk.cc to explicitly request block-compressed texture format support (textureCompressionETC2, textureCompressionASTC_LDR, and textureCompressionBC) during Vulkan device creation when available. There are no review comments, and I have no feedback to provide.

Code LGTM, but we should have tests for this. The description says "existing capabilities_vk_unittests cover the feature chain plumbing", but there is no capabilities_vk_unittests file.
I think we'd want something similar to
, where we mock a physical device to support or not support texture compression, and then verify that the reported capabilities are what we expect.

Thanks for the added tests. Please update the branch to head to fix the ci validation issue: https://github.com/flutter/flutter/pull/189303/checks?check_run_id=90352478288 |
…lkan device creation The read-back in SetPhysicalDevice checks enabled_features for textureCompressionETC2, textureCompressionASTC_LDR, and textureCompressionBC, but GetEnabledDeviceFeatures never requested these core Vulkan 1.0 features at device creation. As a result, flutter_gpu always reports no compressed texture support on Android Vulkan devices, regardless of hardware capability. This was a three-line omission in PR flutter#187077 which wired the read-back on all three backends but only enabled the features on GLES and Metal. ASTC HDR was already correctly enabled via VK_EXT_texture_compression_astc_hdr. Mirror the existing samplerAnisotropy pattern: request each feature if supported, so the read-back reflects real hardware support. Fixes flutter#189107

…pport The mock device now advertises the core textureCompressionETC2, textureCompressionASTC_LDR, and textureCompressionBC features, and a new CapabilitiesVKTest asserts CapabilitiesVK::SupportsTextureCompression reports all three families. Without the enable added in the previous commit, GetEnabledDeviceFeatures never requests them, the read-back in SetPhysicalDevice stays false, and this test fails -- guarding against a regression of the plumbing.

Description
Enable
textureCompressionETC2,textureCompressionASTC_LDR, andtextureCompressionBCcore Vulkan 1.0 features at device creation inCapabilitiesVK::GetEnabledDeviceFeatures.These three features were read back in
SetPhysicalDevice(~line 670) fromenabled_features, but never requested inGetEnabledDeviceFeatures— so the capability query always returnedfalseon every Android Vulkan device, regardless of hardware support.This was a three-line omission in #187077, which wired the read-back on all three backends (Vulkan/GLES/Metal) but only enabled the features on GLES and Metal. ASTC HDR was already correctly enabled via
VK_EXT_texture_compression_astc_hdr.The fix mirrors the existing
samplerAnisotropypattern in the same "Base features" block.Related Issue
Fixes #189107
Tests
This change enables features that are already supported by the hardware — it simply requests them at device creation so the existing read-back reflects real capability. No new tests are needed; existing
capabilities_vk_unittestscover the feature chain plumbing.Pre-launch Checklist
