1 dp = 1/160 inch

But i don\'t what is unit of measu

Answer 1

It all breaks down to device pixel ratio. For instance:

var pixelRatio = MediaQuery.of(context).devicePixelRatio; // 2

And say you're using SizedBox with height: 10, like:

SizedBox(height: 10);

That means your SizedBox would be 2 * 10 = 20dp tall on that device.
