Content of Listview gets drawn over UI elements below in Flutter

Question

Could someone help me with the following issue? I am not sure if this is a bug or intended behaviour. I have the following layout:

Column(
    Flexible( ListView[..] )

    Row(
        Flexible(
            TextField(..) <-- input field
        ),
        Container(Icon[]) <-- button

)

Solution

I believe this is an issue already fixed in dev channel.
