format all textfields the same in flutter

Question

I'm trying to learn Flutter. I have the below TextField setup as I would like it, I could copy and paste all the settings/properties for each TextField in the app, however is there a better way to make all of the TextFields have the same setting/properties?

    Flexible(
        child: Padding(
          padding: EdgeInsets.all(20.0),
          child: TextField(
            maxLength: 5,
            maxLengthEnforcement: MaxLengthEnforcement.enforced,
            keyboardType: TextInputType.numberWithOptions(decimal: true, signed: false, ),
            inputFormatters: [
            FilteringTextInputFormatter.allow(RegExp(r"[0-9.]"))],
            //keyboardType: TextInputType.number,
            decoration: InputDecoration(
              labelStyle: TextStyle(color: Colors.black,
              fontStyle: FontStyle.normal, fontSize: 20, fontWeight: FontWeight.bold ),
              floatingLabelAlignment: FloatingLabelAlignment.center,
              //border: OutlineInputBorder(),
              border: OutlineInputBorder(
              borderRadius: BorderRadius.circular(45),
              ),
              floatingLabelBehavior: FloatingLabelBehavior.always,
              labelText: 'Empty Weight',
              filled: true,
              fillColor: Colors.grey[350],
            ),
          ),
        ),
      ),
