I stored MillisecondsSinceEpoch
in Firestore which is stored in a field as number.
I want to retrieve the data in a Text widget so I convert it to DateTimeFormat.
In the UI everything is good. But in the debug console, I'm getting this error type 'Null' is not a subtype of type 'int'
.
MY CODE
After streamBuild...
final deptTime = snapshot.data?.get("TimeToStart") //I also tried snapshot.data?.get("TimeToStart") ?? ""
final startTime = DateFormat("hh:mm a")
.format((DateTime
.fromMillisecondsSinceEpoch(deptTime)));
.....
Text(startTime)
What can I do to remove the error in the debug console?
Since deptTime
is supposed to receive an Integer value, you shouldn't assign a string to it in case of the field TimeToStart
is null
final deptTime = snapshot.data?.get("TimeToStart")?? DateTime.now().millisecondsSinceEpoch;
...
Note:
the named constructor
DateTime.fromMillisecondsSinceEpoch(intValue)
requires an integer value as a positional parameter.
make sure,
snapshot.data?.get("TimeToStart")
returns an integer if not, cast it to integer.
