I want to change the color of “name” in “Search by name” to Colors.red.shade900. But the hintText field takes String as input. Here is the code for this field:

TextField(
  decoration: InputDecoration(
    hintText: 'Search by name',
    hintStyle: TextStyle(
      fontSize: 16,
      color: Colors.black.withOpacity(0.6),
      fontWeight: FontWeight.w600,
    ),
    prefixIcon: const Padding(
      padding: EdgeInsets.only(left: 8),
      child: Icon(
        Icons.search,
        size: 28,
      ),
    ),
    enabledBorder: OutlineInputBorder(
      borderRadius: BorderRadius.circular(16),
      borderSide: BorderSide(
        color: Colors.black.withOpacity(0.6),
        width: 3,
      ),
    ),
    focusedBorder: OutlineInputBorder(
      borderRadius: BorderRadius.circular(16),
      borderSide: BorderSide(
        color: Colors.black.withOpacity(0.6),
        width: 3,
      ),
    ),
  ),
  style: const TextStyle(
    fontSize: 16,
    color: Colors.black,
    fontWeight: FontWeight.w600,
  ),
),

I have achieved this in regular text:

Using this code:

Text.rich(
  TextSpan(
    children: [
      const TextSpan(
        text: 'Car ',
      ),
      TextSpan(
        text: carId,
        style: TextStyle(
          color: Colors.red.shade900,
        ),
      ),
    ],
    style: const TextStyle(
      fontSize: 28,
      fontWeight: FontWeight.bold,
    ),
  ),
)
