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;

                content_copy

              Common fixes

              #

Change the operand to a Boolean value:

                dart

int a = 3;
bool b = a == 0 || a > 1;
