The expression in an assert must be of type 'bool'.

              Description

              #

              The analyzer produces this diagnostic when the first expression in an
              assert has a type other than `bool`.

              Example

              #

              The following code produces this diagnostic because the type of `p` is
              `int`, but a `bool` is required:

                dart

void f(int p) {
  assert(p);
}

                content_copy

              Common fixes

              #

Change the expression so that it has the type bool:

                dart

void f(int p) {
  assert(p > 0);
}
