prefer_ bool_ in_ asserts
Prefer using a boolean as the assert condition.
Details
#NOTE: This rule is removed in Dart 3.0.0; it is no longer functional.
DO use a boolean for assert conditions.
Not using booleans in assert conditions can lead to code where it isn't clear what the intention of the assert statement is.
BAD:
assert(() {
f();
return true;
});
GOOD:
assert(() {
f();
return true;
}());
