First split the string

var splitTime = inputString.split(":");

Then convert the first value to an int

int hour = int.parse(splitTime[0]);

Check if the hour is greater than 12

String suffix = "am";
if(hour >= 12)
{
hour -= 12;
suffix = "pm";
}

To summarise use this method

String twelveHourVal(String inputString)
{
var splitTime = inputString.split(":");
int hour = int.parse(splitTime[0]);
String suffix = "am";
if(hour >= 12)
{
  hour -= 12;
  suffix = "pm";
 }
String twelveHourVal = '$hour:${splitTime[1]} $suffix';
 return twelveHourVal;
}

Dart intl framework helps you to format date and time into a type you want.

example:

DateFormat("h:mma").format(date);
