使用- prefixIcon: 而不是 icon

TextFormField(
          obscureText: true,

          style: TextStyle(color: Colors.white),
          keyboardType: TextInputType.text,
          //validator: validatePassword,
          decoration: InputDecoration(
            prefixIcon: Icon(
              Icons.lock_outline,
              color: Colors.white,
            ),
              labelStyle: new TextStyle(color: Colors.white),
              enabledBorder: UnderlineInputBorder(
                  borderSide: new BorderSide(color: Colors.white)),
              hintStyle: new TextStyle(
                inherit: true,
                fontSize: 18.0,
                fontFamily: "WorkSansLight",
                color: Colors.white,
              ),
              hintText: 'PASSWORD'),
          onSaved: (String val) {},
        ),
