'How to bypass field does not exist within the DocumentSnapshotPlatform
I'm receiving this error because some of my contents don't have ['ses'] in firestore. Half of the contents have this and the other half do not have it. How can I fix this error? If the content doesn't have ['ses'] in firestore database I just want it to pass, make that variable null. How can I do this?
DetailsPage(
tag: i['timestamp'],
imageUrl:
i['image url'],
category: i['name'],
timestamp:
i['timestamp'],
detay:
i['hakkinda'],
habitat:
i['habitat'],
yayilis:
i['yayilis'],
beslenme:
i['beslenme'],
biyoloji:
i['biyoloji'],
biyoname:
i['biyoname'],
ses: i['ses'])));
Some of the files has "SES" like this one:
Some of the files don't have 'ses':
So Because of this code gave me an error and says "couldn't find 'ses'" and gave this error: field does not exist within the DocumentSnapshotPlatform I want to bypass this, if the file doesn't exist just skip. How can I do this?

Fixed it by using "try {} catch() {}". Here is the code.
onTap: () {
try {
var ses = i['ses'];
Navigator.push(
context,
MaterialPageRoute(
builder: (context) =>
DetailsPage(
tag: i[
'timestamp'],
imageUrl: i[
'image url'],
category:
i['name'],
timestamp: i[
'timestamp'],
detay:
i['hakkinda'],
habitat:
i['habitat'],
yayilis:
i['yayilis'],
beslenme:
i['beslenme'],
biyoloji:
i['biyoloji'],
biyoname:
i['biyoname'],
ses: ses)));
} catch (e) {
Navigator.push(
context,
MaterialPageRoute(
builder: (context) =>
DetailsPage(
tag: i[
'timestamp'],
imageUrl: i[
'image url'],
category:
i['name'],
timestamp: i[
'timestamp'],
detay:
i['hakkinda'],
habitat:
i['habitat'],
yayilis:
i['yayilis'],
beslenme:
i['beslenme'],
biyoloji:
i['biyoloji'],
biyoname:
i['biyoname'],
ses: null)));
}
;
},
