Overview

Check to make sure that if safe navigation is used for a method call in an ‘&&` or `||` condition that safe navigation is used for all method calls on that same object.

Examples:

# bad
foo&.bar && foo.baz

# bad
foo.bar || foo&.baz

# bad
foo&.bar && (foobar.baz || foo.baz)

# good
foo.bar && foo.baz

# good
foo&.bar || foo&.baz

# good
foo&.bar && (foobar.baz || foo&.baz)
