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.
final
automaticallyImplyLeading → bool
final
backgroundColor → Color?
final
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
final
elevation → double?
final
excludeHeaderSemantics → bool
final
flexibleSpace → Widget?
final
foregroundColor → Color?
final
hashCode → int
The hash code for this object.
no setterinherited
icon → IconData?
If we want to override the back button icon, we can do so here
final
iconTheme → IconThemeData?
final
key → Key?
Controls how one widget replaces another widget in the tree.
finalinherited
leadingWidth → double?
final
onTap → (void Function()?)
Override the default onTap behaviour. If this is null, it will default to Navigator.of(context).pop()
final
preferredSize → Size
The size this widget would prefer if it were otherwise unconstrained.
final
primary → bool
final
runtimeType → Type
A representation of the runtime type of the object.
