[Impeller] Compiler crashes when the shader code contains a struct. #138404
Description
Is there an existing issue for this?
- I have searched the existing issues
- I have read the guide to filing a bug
Steps to reproduce
Reference a shader file in pubspec.yaml that defines a GLSL struct and creates an instance of it somewhere in the shader code.
Expected results
The shader compiles successfully, or the compiler shows an error message without crashing.
Actual results
The compiler crashes during the shader compilation.
Code sample
Code sample
In main.dart:
void main {}In shaders/shader.frag:
#version 460 core
#include <flutter/runtime_effect.glsl>
out vec4 fragColor;
struct Color {
vec3 rgb;
};
void main() {
Color color = Color(vec3(1, 0, 0));
fragColor = vec4(color.rgb, 1);
}
Shader is included in pubspec.yaml:
flutter:
shaders:
- shaders/shader.frag
