¿Cómo funciona un widget expandido en flutter?

How does an expanded widget work in flutter?

A widget that expands a child inside a Row or a Column. This widget needs to be used inside a Row or Column widget for it to work properly, it takes up all the available space along its main axis and if all the widgets are wrapped around Expanded widget inside a Row or a Column then space will be divided equally.

When passing layout constraints to its child, padding shrinks the constraints by the given padding, causing the child to layout at a smaller size. Padding then sizes itself to its child’s size, inflated by the padding, effectively creating empty space around the child.

Using an Expanded widget makes a child of a Row, Column, or Flex expand to fill the available space along the main axis (e.g., horizontally for a Row or vertically for a Column ). If multiple children are expanded, the available space is divided among them according to the flex factor.

Flexible widget is basically the same as the Expanded widget, but there is a slight difference in the properties which makes Flexible widget as the name suggests flexible to use. so let’s check out what is all the fuss about…

Flutter layout can’t really be understood without knowing this rule, so I believe everyone should learn it early on. In more detail: A widget gets its own constraints from its parent. A “constraint” is just a set of 4 doubles: a minimum and maximum width, and a minimum and maximum height. Then the widget goes through its own list of children.

Layout objects (eg. Text, Image) only with Row and Column. And Set mainAxisAlignment and crossAxisAlignment property in Row and Column. Set styles with Padding or Align, Expanded etc. You can also use Container. Decorate in addition. https://medium.com/@liewjuntung/tips-on-using-android-studio-to-develop-flutter-apps-9e42c047b7f4

I often build layouts as follows. Layout objects (eg. Text, Image) only with Row and Column. And Set mainAxisAlignment and crossAxisAlignment property in Row and Column. Set styles with Padding or Align, Expanded etc. You can also use Container. Decorate in addition.
