Flapping or tapping, also known as alveolar flapping, intervocalic flapping, or t-voicing, is a phonological process found in many dialects of English, especially North American English, Australian English and New Zealand English, by which the consonant phoneme /t/ or /d/ placed between vowels is pronounced as a voiced flap under certain conditions.
In Wikipedia, it says there can be flapping with both 't' and 'd'. But there are only examples of t-flapping on that page.
Personally, I could realize that I flap 'd' in lots of words.

Do you guys flap 'd' in such words too?
Is it more common to flap it or not?
