Usage of だと
The phrase だと is a conditional expression used to mean "if it is the case that..." or "if...". It often follows a noun, na-adjective, or plain form of verbs and adjectives with the copula だ attached, emphasizing a hypothetical or assumed condition.

Nuances
Using だと adds a nuance of considering a situation as a fact or premise for the following statement. It is more assertive than just と if alone, because of the copula だ.
Common Mistake
Learners sometimes omit だ before と when it is required after nouns or na-adjectives, which can make the sentence sound unnatural or grammatically incorrect. Remember to include だ before と in these cases to form だと.
