Row widget in Flutter uses to display the multiple child widgets in horizontally. Row widget accepts an array of child and you can add any no of widgets.
But when using a row widget there are some tips you need to remember
- Row widget is not a scrollable widget
- Row widget cannot have a more widget than it can show in the available room and it consider as an error.
The row adjusts its size based on the child content. Therefore you can control the height of the row by controlling the height of the child widgets.
If you want to add space between child widget inside a row there are multiples ways to do that.
You Can simply add a SizedBox to add space between widgets.
Adding Spacer widget between the two widgets will also make a space between those widgets. It will take all the available space and align other widgets to the left corner and right corner
There is no direct property to set the background colour to Row widget. But you can wrap row inside a Container and add a background colour to the container
Row normally takes available space and we can control that by wrapping inside a Container or SizedBox widget. You can wrap the Row inside the Container and add width to the container. Then the Row will take the same width as a Container
If you added a widget which can’t fit into the current frame, it will show an error with the yellow strip by saying overflow. This happens because the row widget is not scrollable.
