autoresize text in qml

In the process of studying QML and QtQuick, the following question arose. How can I make the text automatically reduce the font size by decreasing the element in which it is located. Now I have this method 

Rectangle {
id: main_window
width: 700
height: 500

property int main_w: main_window.width

Rectangle {
    width: 400
    height: 400
    anchors.centerIn: parent
    color: 'green'

    Text {
        text: "SIZE ME!!!"
        anchors.centerIn: parent
        color: 'white'
        font.pointSize: {
            if (main_window.main_w < main_window.width)
                return main_window.main_w / 35 // we need 20pt
            return main_window.width / 35
        }
        visible: {
            if (parent.width < 100)
                return false
            return true
        }
    }
}

It works, but not too elegantly. Maybe there are some methods that the text automatically resized. If the wrap in the ColumnLayout does not work.

Please help. Thank you

Here my code with fontSizeMode trying:

Rectangle {
id: root
width: 700
height: 700
property int mrg: 10   

Rectangle {
    anchors.centerIn: parent
    width: 400
    height: 400
    color: 'green'

    Text {
        id: field
        text: "Size me!"
        minimumPointSize: 10
        font.pointSize: 60
        fontSizeMode: Text.Fit
        color: 'white'
        anchors.centerIn: parent
    }
}
}

Problem with the above answers is that if you have a reusable font that you share across your app if you set font.pixel/pointSize it will be changed everywhere which is not wanted to solve that you can create a new font like this:

import QtQuick 

Rectangle {
    id: root
    width: 700
    height: 700
    property int mrg: 10   

    Rectangle {
        anchors.centerIn: parent
        width: root.width * 0.5
        height: root.height * 0.5
        color: 'green'

        Text {
            id: field
            width: parent.width
            height: parent.height
            text: "Size me!"
            color: 'white'
            font: Qt.font({
                        bold: true,
                        underline: false,
                        pixelSize: field.width / 10, // resize relative to parent
                        family: Theme.fFamily,
                })
            anchors.centerIn: parent
        }
    }
}
