Currently, there is no way to get a flexItem instance from a Flex. You can retrieve the underlying primitive using the (*tview.Flex).GetItem method; however, if you want to dynamically modify the proportion or fixedSize of a flexItem, this is not possible. Furthermore, modifying the inner primitive (Item) is not possible either. I propose to export the flexItem struct and add a new method GetFlexItem.

// FlexItem holds layout options for one item.
type FlexItem struct {
	Item       Primitive // The item to be positioned. May be nil for an empty item.
	FixedSize  int       // The item's fixed size which may not be changed, 0 if it has no fixed size.
	Proportion int       // The item's proportion.
	Focus      bool      // Whether or not this item attracts the layout's focus.
}

func (*tview.Flex) GetFlexItem() *FlexItem
