Input instructions on Flutter
When a label might not describe the requested input sufficiently, you should add additional instructions. For example, if passwords are required to be at least 8 characters, indicate this to users.
In Flutter, you can use an InputDecoration
to show instructions for a TextField
. You need to provide a string
for the helperText
property.
TextField(
decoration: InputDecoration(
helperText: 'Your password should be at least 8 characters.',
),
);
