Hi, folks let’s understand the Stack & IndexedStack in Flutter.
The stack widget contains a list of widgets and places them on top of each other. And it places their children on top of each other like a stack of books. In other words, the stack widget would overlap multiple widgets on one screen. As you can add different images or colors using containers in it.
–> It basically determines the placement of the Non-positioned Widget available in Stack.
–> One can change the direction of text, whether it should start from left to right (LTR) or right to left (RTL). Which becomes quite handy while working with multiple languages.
–> This property decided how the non-positioned children in the Stack will fill the space available.
–> fit has three types of StackFit.loose, StackFit.expand, StackFit.passthrough
–> To manage whether the overflowing content of the child widget should be clipped, or remain as it is, like-: visible.
The Positioned widgets are related to the position of some widgets. The right-positioned widgets allow us to control this. A child of that stack is positioned on the inside of the stack.
height: we can give a specific height to a widget.
width: we can give a specific width to a widget.
left: set margin/padding from the left side of the widget.
right: set margin/padding from the right side of the widget.
top: set margin/padding from the top side of the widget.
bottom: set margin/padding from the bottom side of the widget.
An IndexedStack is a stack where only one component is shown at one time by its index. A Stack that shows a solitary child from a list of children. The showed child is the one with the given index. The stack is consistently just about as large as the biggest child. On the off chance that the value is null, nothing is shown.
alignment: The non-positioned and partially-positioned children in the stack are aligned using these attributes.
text direction: These properties are used to determine alignment based on the text direction.
sizing: The non-positioned children in the stack are sized using these properties.
index: These attributes are used to display the child’s index.
children: The List uses these properties.
That’s all for this Article 🎊 .
