    await cGetDeviceId()
   

5. Takes a screenshot of a widget using a [GlobalKey] and returns it as a [Uint8List] (PNG image).

    cTakePicture(GlobalKey);
    // wrap with RepaintBoundary then use key to create image
    RepaintBoundary(
        key: GlobalKey,
        child:Text('data'),
    )
   

6. flutter platform

   just call these functions anywhere

Make a responsive gridView by using both 1 and 2

provide discardSize to minus size from calculation

1. Based on your static design's width, calculate the responsive grid item count.

   crossAxisCount: cGetResCrossCountGrid(
       context: context,
       width: 180,
   ),
   

2. For responsive grid item aspect ratio, it should be derived from your static design based on height and width.

   childAspectRatio: cGetResGridRatio(
       context: context,
       height: 165,
       width: 180,
   ),
   

3. For normal grid aspect ratio > Having this aspect ratio will never break in larger or smaller devices

   crossAxisCount: 2,
   childAspectRatio: cGetGridRatio(
       crossAxisCount: 2,
       context: context,
       height: 165,
       width: 180,
   ),
   

   Your provided height and width determine how it works

    cFormUrlEncode({'':''});

1. For duration and delay

       void splash() {
           // cDays, cHours, cMinutes, cSeconds, cMilliseconds
           2.cSeconds.cDelay(() {
               // code here
           });
   
           // given number in seconds
           3.cDelay(() {
               // code here
           });
       }

1. An extension for nullable [TimeOfDay] objects, providing a method to convert them to a formatted string in AM/PM format or display 'Invalid date' if the [TimeOfDay] object is null.

   cTimeOfDayToString()

   TimeOfDay? timeOfDay = TimeOfDay(hour: 14, minute: 30);
   String formattedTime = timeOfDay.cTimeOfDayToString();
   print(formattedTime); // Output: "2:30 PM"
   
   timeOfDay = null;
   formattedTime = timeOfDay.cTimeOfDayToString();
   print(formattedTime); // Output: "Invalid date"
   

2. This method attempts to parse the input string in both 12-hour and 24-hour time formats and returns a [TimeOfDay] object if parsing is successful, or null if the string cannot be parsed as a valid time.

   cToTimeOfDay()

   String timeString = "2:30 PM";
   TimeOfDay? timeOfDay = timeString.cToTimeOfDay();
   
   if (timeOfDay != null) {
       print("Parsed time: $timeOfDay");
   } else {
       print("Invalid time format");
   }
   

3. This method combines the date part of the current [DateTime] instance with the hour and minute components from the provided [time].

   cApplied()

   final date = DateTime.now();
   final time = TimeOfDay(hour: 15, minute: 30);
   final combinedDateTime = date.cApplied(time);
   print(combinedDateTime); // Output: 2023-09-15:30:00.000
   

4. Optionally, you can provide a custom [format] string to specify the desired date format. If [format] is not provided, the default format dd/MM/yyyy will be used.

   cGetFormattedDate()

   final date = DateTime.now();
   final formattedDate = date.cGetFormattedDate(format: 'MM-dd-yyyy');
   print(formattedDate); // Output: 09-13-2023
   

   OR

   String date = '2023-09-13';
   String formattedDate = date.cGetFormattedDate(format: 'MMMM d, y');
   // Result: 'September 13, 2023'
   

5. This method calculates the difference between the current [DateTime] instance and the current date and time and provides an aging description.

   cDateToAging()

   final pastDate = DateTime(2022, 3, 10);
   final agingString = pastDate.cDateToAging();
   print(agingString); // Output: "1 year ago"
   

   OR

   String date = '2023-08-01T12:34:56';
   String agingDescription = date.cDateToAging();
   // Result: '1 month ago'
   

6. Converts a string representation of a date and time into a [DateTime] object.

   cGetDateFromString()

   // Example date and time string
   String dateString = "2023-09-26 14:30:00";
   // Attempt to parse the date string into a DateTime object
   DateTime? dateTime = dateString.cGetDateFromString();
   // Check if parsing was successful
   if (dateTime != null) {
    print("Parsed DateTime: $dateTime");
   } else {
    print("Failed to parse the string as DateTime.");
   }

1. This extension provides a method to convert a Flutter Color object to its hexadecimal representation with an optional leading hash sign. The resulting hexadecimal string includes the alpha, red, green, and blue components of the color.

   final color = Color(0xFF42A5F5);
   final hexString = color.cToHex(); // Returns: "#FF42A5F5"
   

2. This extension provides a method to convert a hexadecimal color code represented as a String into a Flutter Color object. The color code can optionally include a leading hash sign ('#'). If the input color code has 6 or 7 characters (with or without the hash sign), the method will assume it represents a color with an alpha component and append 'ff' to the color code to make it fully opaque.

   final colorCode = '#FF42A5F5';
   final color = colorCode.cToColor(); // Returns: Color(0xFF42A5F5)
