non_bool_condition
Conditions must have a static type of 'bool'.
Description
#The analyzer produces this diagnostic when a condition, such as an if
or while
loop, doesn't have the static type bool
.
Example
#The following code produces this diagnostic because x
has the static type int
:
dart
void f(int x) {
if (x) {
// ...
}
}
Common fixes
#Change the condition so that it produces a Boolean value:
dart
void f(int x) {
if (x == 0) {
// ...
}
}
