Communism101

From what I gather, Dialectical analysis is the opposite of metaphysical analysis. I also know Idealism is the other side of materialism. So I feel like Idealism and Metaphysics go hand in hand. They are ways of thinking that fundamentally go against the way the world works in a DialMat perspective. I’m mainly confused because I basically see DialMat as one in the same when I know they aren’t. Can you give me an example of what a Metaphysical Materialist would look like? Or what a Dialectical understanding Idealist would look like as opposed to the former? I should probably brush up on Anarchism or Socialism by Stalin just to make sure but any input is appreciated comrades.
