QML: Dynamic resizing main window based on item appended to listmodel

AexAcad

Hi, I am working on a chat based application where I am trying to resize / grow the height of the main window when text is appended to the listmodel based on the message box height.

The listmodel is in a seperate file to which I am appending through input from textfield and property alias. The main.qml where the listmodel qml is displayed:

Main.qml: 

ApplicationWindow {
    id: root
    width: 450
    minimumHeight: 75
    visible: true
    color: "#373131"

SwipeView {
id: swipev

Page{
            id: page1

Rectangle {
                id: rectangle2
                color: "#272131"
                anchors.left: parent.left
                anchors.leftMargin: 0
                anchors.bottom: parent.bottom
                anchors.bottomMargin: 0
                anchors.top: parent.top
                anchors.topMargin: 0
                anchors.right: rectangle3.left
                anchors.rightMargin: 0

                ConvoView { id: conview
                    anchors.right: rectangle2.right
                }

            }
        }
    }
}

Listmodel and Listview where the appended text is added to the messagerow.

ConvoView.qml

Item {
    id: item1
    property alias inmsg: conversationList

 ListModel{
    id: conversationList
    }

 ListView{
... 
delegate: Column {
                        spacing: 6
                        anchors.right: parent.right

                        Row {
                            id: messageRow
                            spacing: 6

                            Rectangle {
                                width: messageText.implicitWidth + 24
                                height: messageText.implicitHeight + 24
                                color: "lightgrey"

                                Label {
                                    id: messageText
                                    text: model.InputQuery
                                    color: "black"
                                    anchors.fill: parent
                                    anchors.margins: 12
                                    wrapMode: Label.Wrap
                                    }

                                }   
        
                            }
                        }
}

How can I set the height of the window to grow as the messages appended increases? I know i can set a fixed height and use a scrollbar but that's what I want to avoid. Is there any documentation i can find about dynamic resizing or resources/examples i can refer too ? Please help.
