OutlineButton class
A cross between RaisedButton and FlatButton: a bordered button whose elevation increases and whose background becomes opaque when the button is pressed.
An outline button's elevation is initially 0.0 and its background color is transparent. When the button is pressed its background becomes opaque and then its elevation increases to highlightElevation.
The outline button has a border whose shape is defined by shape and whose appearance is defined by borderSide, disabledBorderColor, and highlightedBorderColor.
If the onPressed callback is null, then the button will be disabled and by default will resemble a flat button in the disabledColor.
If you want an ink-splash effect for taps, but don't want to use a button, consider using InkWell directly.
Outline buttons have a minimum size of 88.0 by 36.0 which can be overidden with ButtonTheme.
