/// A flat button is a text label displayed on a (zero elevation) [Material]
/// widget that reacts to touches by filling with color.
///
/// Use flat buttons on toolbars, in dialogs, or inline with other content but
/// offset from that content with padding so that the button's presence is
/// obvious. Flat buttons intentionally do not have visible borders and must
/// therefore rely on their position relative to other content for context. In
/// dialogs and cards, they should be grouped together in one of the bottom
/// corners. Avoid using flat buttons where they would blend in with other
/// content, for example in the middle of lists.
///
/// Material design flat buttons have an all-caps label, some internal padding,
/// and some defined dimensions. To have a part of your application be
/// interactive, with ink splashes, without also committing to these stylistic
/// choices, consider using [InkWell] instead.
///
/// If the [onPressed] and [onLongPress] callbacks are null, then this button will be disabled,
/// will not react to touch, and will be colored as specified by
/// the [disabledColor] property instead of the [color] property. If you are
/// trying to change the button's [color] and it is not having any effect, check
/// that you are passing a non-null [onPressed] handler.
///
/// Flat buttons have a minimum size of 88.0 by 36.0 which can be overridden
/// with [ButtonTheme].
///
/// The [clipBehavior] argument must not be null.
