As a beginner in Application development using flutter, we get confused in understanding widgets and their uses. we got the pre-written counter application code when we generate a flutter application. We can notice there are so many widgets in a simple application e.g. Scaffold, Column, Container, Text, floating action button, and many more. As a beginner, we have to understand the basic difference between Column and ListView. The major difference between these two is the former one has definite height on a screen and the later one can have much more height to show according to need. After this, we can fit as many widgets inside both Column and ListView.
