sdk_version_gt_gt_gt_operator
The operator '>>>' wasn't supported until version 2.14.0, but this code is required to be able to run on earlier versions.
Description
#The analyzer produces this diagnostic when the operator >>>
is used in code that has an SDK constraint whose lower bound is less than 2.14.0. This operator wasn't supported in earlier versions, so this code won't be able to run against earlier versions of the SDK.
Example
#Here's an example of a pubspec that defines an SDK constraint with a lower bound of less than 2.14.0:
environment:
sdk: '>=2.0.0 <2.15.0'
In the package that has that pubspec, code like the following produces this diagnostic:
int x = 3 >>> 4;
Common fixes
#If you don't need to support older versions of the SDK, then you can increase the SDK constraint to allow the operator to be used:
environment:
sdk: '>=2.14.0 <2.15.0'
If you need to support older versions of the SDK, then rewrite the code to not use the >>>
operator:
int x = logicalShiftRight(3, 4);
int logicalShiftRight(int leftOperand, int rightOperand) {
int divisor = 1 << rightOperand;
if (divisor == 0) {
return 0;
}
return leftOperand ~/ divisor;
}
