Bar Chart

A Bar Chart is a way of representing data through rectangular bars and it is also used to make the chart in either Horizontal or Vertical Direction.

By default, Bar Chart is created in Vertical Direction.

If order to add labels, within our rectangular bars, we can add a property named ‘barRendererDecorator’.

To make the Horizontal Bar Chart, you can set the vertical property to ‘false’.

Line Chart

Line Chart is one which represents the data in the form of lines.

Pie Chart

A pie chart is a chart that is circular in shape and is divided into multiple sections based on the percentage.

To add the labels in the Pie Chart, we can use the ‘labelPosition’ property of ‘defaultRenderer’.

You can even choose to add your labels inside or outside the Pie Chart as per your requirement.

Therefore, in this way, you can create different types of charts as per your requirement in the Flutter Application.
