The Transform widget gives us a few constructors to help simplify the creation of transformations. Let’s start with the types of Transform widgets. This can be used to transform any widget and distort it to any shape we like or move it around as well. This is extremely useful for custom shapes and many different kinds of animations in Flutter. TransformĪ Transform widget “transforms” (i.e. changes the shape, size, position and orientation) its child widget before painting it.ĭistorting the shape of the container using Transform There cannot be another widget in between the stack and the widget. Note: Positioned has to be a child of a Stack.
Let’s simply wrap our containers in an Align and then a Positioned widget. We’ll alter our example to use Align and Positioned. A Positioned widget combines these two things and lets us keep one Positioned widget instead of an Align and a Padding. So for example, if we enter top-right, we need to add extra padding to keep it neat and tidy. To change this, you can align or position your widget using the Align or Positioned widget.Īn Align widget usually takes widget to extreme positions. If you notice, the containers which are smaller have a lot more area to go to and hence default to top left. So if the bottom layer covers the complete screen then the size of the Stack is the complete screen.Įach member in the stack needs to be positioned or aligned, or else it ends up in the top left corner by default.Īs an example, let’s take three containers of shrinking size: Stack( The size of the Stack is the size of the largest member in the layer. So the first item is the bottom-most and the last is the topmost. The widget takes multiple children and orders them from bottom to top. The Stack the widget allows us to put up multiple layers of widgets onto the screen. To achieve this complexity we have to learn about this triangleĪs mentioned in that figure, a complex triangle consists of 3 different components.
