CodePudding user response：

When executing the SignUp function (at Material Button OnPressed), are the variables passed in the wrong order?

CodePudding user response：

It's almost always trailing whitespace, try:

postDetailsToFirestore(
            email.trim(),
            role,
            name,
            vehicleNo,
          ),

Alternatively you can also try to hardcode the right email address and check whether the problem is in logic or in UI.
