'How to define conditional text color in Text widget Flutter

Here is my code

I want to get specific color when nDataList.temp >= temp

flutter dart

Solution 1:^[1]

I think your issue is related to null safety if nDataList.temp allows null you can't do the check as you did, the solution could be

Text(
  (nDataList.temp ?? 0) >= temp ? 'Normal' : 'Not Normal',
  style: const TextStyle(
    fontWeight: FontWeight.bold,
    fontSize: 12,
    color: (nDataList.temp ?? 0) >= temp ? Colors.white : Colors.red,
  ),
),

Solution 2:^[2]

Try this in your commandline:

First, flutter clean

Then flutter run

Solution 3:^[3]

thanks all, my problem in const before TextStyle() widget
