GD0103: The exported member is read-only

==================================== ====================================== Value ==================================== ====================================== Rule ID GD0103 Category Usage Fix is breaking or non-breaking Non-breaking Enabled by default Yes ==================================== ======================================

Cause

A read-only member is annotated with the [Export] attribute. Read-only members can't be exported.

Rule description

Redot doesn't allow exporting read-only members.

// Read-only fields can't be exported.
[Export]
public readonly int invalidField;

// This field can be exported because it's not declared 'readonly'.
[Export]
public int validField;

// Read-only properties can't be exported.
[Export]
public int InvalidProperty { get; }

// This property can be exported because it has both a getter and a setter.
[Export]
public int ValidProperty { get; set; }

How to fix violations

To fix a violation of this rule for fields, remove the readonly keyword or remove the [Export] attribute.

To fix a violation of this rule for properties, make sure the property declares both a getter and a setter, or remove the [Export] attribute.

When to suppress warnings

Do not suppress a warning from this rule. Read-only members can't be exported so they will be ignored by Redot, resulting in runtime errors.
