This is a basic appBar that eliminates any default AppBar styling, and has a transparent background and shadow colour, black icon colour and 0 elevation.

Besides this, everything else is identical to the Flutter default AppBar component

Properties

actions List<Widget>?
final
actionsIconTheme IconThemeData?
final
adaptiveBackButton bool
If true, this widget uses Icons.arrow_back_ios_new on iOS or macOS, and Icons.arrow_back on everything else. Note that specifying icon will override this.

backwardsCompatibility bool?
final
bottom PreferredSizeWidget?
final
bottomOpacity double
final
brightness Brightness?
final
centerTitle bool?
final
disabled bool
If true, the leading icon button will be in a disabled state. This is needed because the onTap parameter defaults to the default onBack behaviour specified in the Pueprint if null
