Awesome Flutter Snippets is a collection of commonly used Flutter classes and methods. It increases your speed of development by eliminating most of the boilerplate code associated with creating a widget. Widgets such as StreamBuilder and SingleChildScrollView can be created by typing the shortcut streamBldr and singleChildSV respectively.

Features

• Speeds up development
• Eliminates boilerplate
• Supports complex widgets (Eg: Custom Clipper and Custom Paint)

 

Shortcut	Expanded	Description
statelessW	Stateless Widget	Creates a Stateless widget
statefulW	Stateful Widget	Creates a Stateful widget
build	Build Method	Describes the part of the user interface represented by the widget.
initS	InitState	Called when this object is inserted into the tree. The framework will call this method exactly once for each State object it creates.
dis	Dispose	Called when this object is removed from the tree permanently. The framework calls this method when this State object will never build again.
reassemble	Reassemble	Called whenever the application is reassembled during debugging, for example during hot reload.
didChangeD	didChangeDependencies	Called when a dependency of this State object changes
didUpdateW	didUpdateWidget	Called whenever the widget configuration changes.
customClipper	Custom Clipper	Used for creating custom shapes
customPainter	Custom Painter	Used for creating custom paint
listViewB	ListView.Builder	Creates a scrollable, linear array of widgets that are created on demand.Providing a non-null itemCount improves the ability of the ListView to estimate the maximum scroll extent.
listViewS	ListView.Separated	Creates a fixed-length scrollable linear array of list 'items' separated by list item 'separators'.
gridViewB	GridView.Builder	Creates a scrollable, 2D array of widgets that are created on demand. Providing a non-null itemCount improves the ability of the GridView to estimate the maximum scroll extent.
gridViewC	GridView.Count	Creates a scrollable, 2D array of widgets with a fixed number of tiles in the cross axis.
gridViewE	GridView.Extent	Creates a scrollable, 2D array of widgets with tiles that each have a maximum cross-axis extent.
customScrollV	Custom ScrollView	Creates a ScrollView that creates custom scroll effects using slivers. If the primary argument is true, the controller must be null.
streamBldr	Stream Builder	Creates a new StreamBuilder that builds itself based on the latest snapshot of interaction with the specified stream
animatedBldr	Animated Builder	Creates an Animated Builder. The widget specified to child is passed to the builder
statefulBldr	Stateful Builder	Creates a widget that both has state and delegates its build to a callback. Useful for rebuilding specific sections of the widget tree.
orientationBldr	Orientation Builder	Creates a builder which allows for the orientation of the device to be specified and referenced
layoutBldr	Layout Builder	Similar to the Builder widget except that the framework calls the builder function at layout time and provides the parent widget's constraints.
singleChildSV	Single Child Scroll View	Creates a scroll view with a single child
futureBldr	Future Builder	Creates a Future Builder. This builds itself based on the latest snapshot of interaction with a Future.
nosm	No Such Method	This method is invoked when a non-existent method or property is accessed.
inheritedW	Inherited Widget	Class used to propagate information down the widget tree.
mounted	Mounted	Whether this State object is currently in a tree.
snk	Sink	A Sink is the input of a stream.
strm	Stream	A source of asynchronous data events. A stream can be of any data type.
subj	Subject	A BehaviorSubject is also a broadcast StreamController which returns an Observable rather than a Stream.
toStr	To String	Returns a string representation of this object.
debugP	Debug Print	Prints a message to the console, which you can access using the flutter tool's logs command (flutter logs).
importM	Material Package	Import Material package.
importC	Cupertino Package	Import Cupertino package.
importFT	flutter_test Package	Import flutter_test package.
importAL	App localisation	Allows for the importation of app_localisation following generation.
mateapp	Material App	Create a new Material App.
cupeapp	Cupertino Package	Create a New Cupertino App.
tweenAnimationBuilder	Tween Animation Builder	Widget builder that animates a property of a Widget to a target value whenever the target value changes.
valueListenableBuilder	Value Listenable Builder	Given a ValueListenable and a builder which builds widgets from concrete values of T, this class will automatically register itself as a listener of the ValueListenable and call the builder with updated values when the value changes.
f-group	Group	Create a group test function.
f-test	Test	Create a test function.
f-testWidgets	Test Widgets	Create a testWidgets function.
