Interface: ExpressionEditorSlotProps

Defined in: packages/visual-editor/src/types.ts:143

Props provided to the expression editor render-prop slot.

packages/visual-editor is editor-agnostic — the host app provides the actual editor implementation (e.g. CodeMirror, Monaco) via a renderExpressionEditor prop on FunctionForm.
