是否可以在flutter中的TextField上使用渐变？

TextField(
  decoration: InputDecoration(
    labelText: 'Enter your name',
    border: OutlineInputBorder(),
    filled: true,
    fillColor: Colors.white,
    focusedBorder: OutlineInputBorder(
      borderSide: BorderSide(color: Colors.blue),
      borderRadius: BorderRadius.circular(10),
    ),
    enabledBorder: OutlineInputBorder(
      borderSide: BorderSide(color: Colors.grey),
      borderRadius: BorderRadius.circular(10),
    ),
    // 渐变
    gradient: LinearGradient(
      colors: [Colors.red, Colors.blue],
      begin: Alignment.topLeft,
      end: Alignment.bottomRight,
    ),
  ),
)
