proposal: `no_write_only_initialization`

4

## no_write_only_initialization ## Description A write only field may be tree-shaken away, but if it is not `late` its initialization code will be inlined into the constructor. This can negatively...

[Impeller] Investigate runtime flag for Impeller toggling

9

customer: money is interested in experimenting with Impeller on iOS (pending development verification of visual correctness). It would probably be easier for them to run an experiment if they can...

[Impeller] Expose dashed path effect.

1

Impeller will be able to do path dashing much more quickly than the concerns we had with Skia. This should be low priority, but the current methods of dashing a...

[Impeller] Tessellation for Bezier curves doesn't look too great when scaled.

2

```cpp TEST_F(EntityTest, BezierCircleScaled) { Entity entity; auto path = PathBuilder{} .MoveTo({97.325, 34.818}) .CubicCurveTo({98.50862885295136, 34.81812293973836}, {99.46822048142015, 33.85863261475589}, {99.46822048142015, 32.67499810206613}) .CubicCurveTo({99.46822048142015, 31.491363589376355}, {98.50862885295136, 30.53187326439389}, {97.32499434685802, 30.531998226542708}) .CubicCurveTo({96.14153655073771, 30.532123170035373}, {95.18222070648729, 31.491540299350355}, {95.18222070648729, 32.67499810206613})...

[Impeller] Trying to access the `length()` of a SSBO in a compute shader doesn't do the right thing

2

I'm working up updating/fixing the sample.comp shader. This line isn't currently safe: https://github.com/flutter/engine/blob/3c4af1da0c3e76b2957db4efdd44604b0342d1ab/impeller/fixtures/sample.comp#L19 Because with too little data or too many threads, it will do OOB accesses. I'd like to...

[Impeller] Compiler fails to print out shaderc error message in cases where an error occurs with 0 errors and 0 warnings.

2

I found this while tweaking //impeller/compiler/compiler.cc to test something using a higher SPIRV version than 1.0. In this case, I had misconfigured the Vulkan version for the SPIRV version I...

Provide a pluggable method for asset transformation

23

The tool already does transformation of icon fonts at build time. It would be good to make an interface like that open and pluggable, so that packages external to the...

[Impeller] vkDestroyPipeline gets called too early sometimes on Vulkan

Error looks like this: ``` E/flutter (21891): [ERROR:flutter/impeller/base/validation.cc(49)] Break on 'ImpellerValidationBreak' to inspect point of failure: E/flutter (21891): --- Vulkan Debug Report ---------------------------------------- E/flutter (21891): | Severity: Error E/flutter (21891):...

Refactors `ShaderTarget` to make it opaque as to whether it's using Impeller or SkSL and instead has it focus on the target platform it's generating for. ImpellerC includes SkSL right...
