//***************************************************************************
//* ▼▼▼▼▼▼▼▼ description ▼▼▼▼▼▼▼▼ (do not modify or remove section marker)

// This example covers most of the attributes available in Tooltip.
// `decoration` has been used to give a gradient and borderRadius to Tooltip.
// `height` has been used to set a specific height of the Tooltip.
// `preferBelow` is false, the tooltip will prefer showing above [Tooltip]'s child widget.
// However, it may show the tooltip below if there's not enough space
// above the widget.
// `textStyle` has been used to set the font size of the 'message'.
// `showDuration` accepts a Duration to continue showing the message after the long
// press has been released or the mouse pointer exits the child widget.
// `waitDuration` accepts a Duration for which a mouse pointer has to hover over the child
// widget before the tooltip is shown.
