Severity:
Missing Address Zero Checks in ‘SablierFlow::_create' Function
Summary
The _create function in SablierFlow.sol does not currently check if the recipient address is set to the zero address (address(0)), which is a requirement according to the documentation in the ISablierFlow.sol interface. This missing check can lead to unintended behavior, as it allows flows to be created with an invalid recipient.
Recommendations
To resolve this issue, add a check in _create to ensure that the recipient address is not address(0). This validation will prevent flows from being created with an invalid recipient.
