Booleans and Comparison Operators

Produce true and false from comparisons.

Yes or No, True or False

Every decision your program makes starts with a yes-or-no answer. In Dart that answer is a bool, which holds only true or false. 🤔

You store a yes-or-no value in a variable typed as bool. It can hold the literal true or the literal false, and nothing else.

bool isReady = true;
bool isDone = false;
