A header bar intended for use by mobile apps. The header bar has a label, which is displayed as its title, along with a set of actions. Each action has a name, which is used to identify it internally, and an icon and label which are displayed (depending on the chosen itemStyle). One of the actions can optionally be displayed to the left of the header bar's title, when the firstItemLeft property is enabled. The header bar widget provides two theme modes, one for Android apps and one for iOS apps. By default, it automatically selects the appropriate one depending on which platform it is running on. To temporarily select a non-default different appearance, set the theme property. The header bar widget works well when paired with the navigation bar widget.
