border property
The shape of the border to be drawn around the InputField can be defined using the border variable.
This variable can take on several different values including:
InputBorder.none, which means no border will be drawn.
UnderlineInputBorder, which draws a horizontal line at the bottom of the InputField.
OutlineInputBorder, which results in a rounded rectangle being drawn around the InputField.
note that: if border property of the inputTheme
is not equal InputBorder.none, the border of CountryListPicker will be canceled.
