> Custom layout to help layout child widgets using flex layout.

* **This class is a JS wrapper around custom Qt layout implemented using [Yoga](https://github.com/facebook/yoga)**

A `FlexLayout` can be used to layout all child Vixen widgets using flex.

### Example

```javascript
import { FlexLayout, QWidget, QLabel } from "@vixen-js/core";

const view = new QWidget();
const layout = new FlexLayout();
view.setLayout(layout);

const label = new QLabel();
label.setText("label1");
const label2 = new QLabel();
label2.setText("label2");

layout.addWidget(label);
layout.addWidget(label2);
```

    protected flexNode?: FlexNode;
    constructor(parent?: QWidget);
    addWidget(childWidget: QWidget, childFlexNode?: FlexNode): void;
    insertChildBefore(childWidget: QWidget, beforeChildWidget: QWidget, childFlexNode?: FlexNode, beforeChildFlexNode?: FlexNode): void;
    removeWidget(childWidget: QWidget, childFlexNode?: FlexNode): void;
    setFlexNode(flexNode: FlexNode): void;
    getChildIndex(childWidget: QWidget): number;
    getNextSibling(childWidget: QWidget): QWidget | null;
