VertexAttributeDescriptor class

A described vertex attribute: the shader input it feeds (by name), its element format, and its byte offsetInBytes within the owning buffer's per-element stride.

This is the engine-side, value-equal description of a single attribute. It lowers to a gpu.VertexAttribute (the flutter_gpu pipeline type) but, unlike that type, compares by value so two structurally identical layouts can be interned to one identity (see vertexLayoutId).

Properties

format → VertexFormat

Format of each element of this attribute.

final

hashCode → int

The hash code for this object.

no setter, override

name → String

Name of the shader-side input this attribute feeds (e.g. position). flutter_gpu binds vertex attributes by name, so this must match the vertex shader's in declaration.

final

offsetInBytes → int

Byte offset of this attribute from the start of each element of the owning VertexBufferDescriptor.

final

runtimeType → Type

A representation of the runtime type of the object.

no setter, inherited

Methods

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

toString() → String

A string representation of this object.

inherited

Operators

operator ==(Object other) → bool

The equality operator.
