What are the important attributes/properties of TextFormField in Flutter can someone tell me?

CodePudding user response：

You can study the constructor about TextFormField

Here is the example of TextFormField

TextFormField(
  decoration: InputDecoration(
    isDense: true,
    labelText: labelText,
    labelStyle: TextStyle(fontFamily: "ROCK", color: labelColor),
    floatingLabelBehavior: FloatingLabelBehavior.always,
  
    focusedBorder: OutlineInputBorder(
        borderSide: BorderSide(color: borderColor!),
        borderRadius: BorderRadius.circular(15)),
    enabledBorder: OutlineInputBorder(
        borderSide: BorderSide(color: borderColor!),
        borderRadius: BorderRadius.circular(15)),
  ),
);
