non_bool_operand
Details about the 'non_bool_operand' diagnostic produced by the Dart analyzer.
The operands of the operator '{0}' must be assignable to 'bool'.
Description
#
The analyzer produces this diagnostic when one of the operands of either
the && or || operator doesn't have the type bool.
Example
#
The following code produces this diagnostic because a isn't a Boolean
value:
dart
int a = 3;
bool b = a || a > 1;
Common fixes
#Change the operand to a Boolean value:
dart
int a = 3;
bool b = a == 0 || a > 1;
