I am new to flutter and I am having a difficult challenge to perform two if conditions. All I want to achieve is to perform an if statement on two boolean conditions in the the array below. I want to check if Success == true && Stock['Submitted'] == true, then its should display a button labelled "Validate farmers" but if these two conditions did not hold true then it should show a button labelled "Take Inventory". But its not working. Please how can i access the Submitted Value?
this is the structure of the arry:
{
"StatusCode": 200,
"Message": "Record Found",
"Success": true,
"Stock": {
"Oid": 30,
"CreatedBy": "johndoh",
"CreatedOn": "2020-07-07T10:28:19.09",
"ModifiedBy": null,
"ModifiedOn": null,
"Season": null,
"SeasonTitle": null,
"Anchor": 11,
"AnchorName": null,
"AnchorAcronym": null,
"DistributionCentre": 11,
"DistributionCentreName": null,
"Agent": "John Doh",
"StateCoordinator": "Godwin Obute",
"StockDate": "2020-07-07T10:27:49.03",
"TransId": "20200707102819089",
"StateCoordinatorId": "38",
"AgentId": "57",
"UserId": "b6caf34c-a425-4710-a3ee-aa22a382882a",
"Submitted": false,
"SubmittedOn": null,
"SubmittedBy": null,
"StockItems": []
}
}
A Function that calls the http request which returns the array above just after my stateful widget state:
var user;
var userData;
var userDetail;
var anchors;
var dailyStatus;
var dailyStocks;
var found = false;
var stockoid;
// var dataSubmitted = false;
@override
void initState() {
_getUserInfo();
super.initState();
}
//This getuser info gives me the parameters to use on the checkinventorystatus
void _getUserInfo() async {
SharedPreferences localStorage = await SharedPreferences.getInstance();
var userJson = localStorage.getString('loginRes');
user = json.decode(userJson);
userDetail = user['UserDetail'];
print('${userDetail['Oid']} poii'); //Just to get the userId
anchors = user['Anchors'];
setState(() {
userData = user;
print('${userData['UserId']} ioo');
// var dc = value['DistributionCentres'][1]['Oid'];
// print(dc);
});
}
//This is the main function that gives me the array above
Future<CheckInventoryStatus> checkDailyStatus() async {
final response = await http.get(
'http://api.ergagro.com:112/CheckDailyStockTakingStatus?userId=${userData['UserId']}&agentId=${userDetail['Oid']}',
headers: {
'Content-type': 'application/json',
'Accept': 'application/json',
});
if (response.statusCode == 200) {
found = true;
final jsonStatus = jsonDecode(response.body);
var stock = jsonStatus['Stock'];
bool submitted = stock['Submitted'];
stockoid = stock['Oid'].toString();
setState(() {
found = submitted;
});
return CheckInventoryStatus.fromJson(jsonStatus);
} else {
throw Exception();
}
}
This is my Widget View:
after my children widget:
Row(
children: <Widget>[
/////////// Based on the response I want to use it to control these two buttons below
///if the response is 200 it should display validate farmer else it should display Take Inventory/////////////
Padding(
padding: const EdgeInsets.all(10.0),
//this is where I want to perform the check but its not working
// dailyStatus['StatusCode'] == 200
child: found
? FlatButton(
child: Padding(
padding: EdgeInsets.only(
top: 8, bottom: 8, left: 10, right: 10),
child: Text(
'Validate Farmers',
textDirection: TextDirection.ltr,
style: TextStyle(
color: Colors.white,
fontSize: 15.0,
decoration: TextDecoration.none,
fontWeight: FontWeight.normal,
),
),
),
color: Colors.green,
shape: new RoundedRectangleBorder(
borderRadius: new BorderRadius.circular(20.0)),
onPressed: () {
Navigator.push(
context,
new MaterialPageRoute(
builder: (context) => StartScanPage()));
// Edit()was here
},
)
//if the status is not 200 then it should allow an agent to take inventory
: FlatButton(
child: Padding(
padding: EdgeInsets.only(
top: 8, bottom: 8, left: 10, right: 8),
child: Text(
'Take Inventory',
textDirection: TextDirection.ltr,
style: TextStyle(
color: Colors.white,
fontSize: 15.0,
decoration: TextDecoration.none,
fontWeight: FontWeight.normal,
),
),
),
color: Colors.blueGrey,
shape: new RoundedRectangleBorder(
borderRadius: new BorderRadius.circular(20.0)),
onPressed: () {
Navigator.push(
context,
new MaterialPageRoute(
builder: (context) => StockInventoryPage(
userData['UserId'],
'${userDetail['Oid']}',
'${value['DistributionCentres'][i]['Oid']}',
stockoid)));
},
),
),
/////////// End of Buttons /////////////
],
),
How about Something like this:
Widget _showButton(bool firstCondition, bool seacondCondition) {
return Padding(
padding: const EdgeInsets.all(10.0),
child: FlatButton(
child: Padding(
padding: EdgeInsets.only(top: 8, bottom: 8, left: 10, right: 10),
child: Text(
(firstCondition && seacondCondition)?'Validate Farmers':'Take Inventory',
textDirection: TextDirection.ltr,
style: TextStyle(
color: Colors.white,
fontSize: 15.0,
decoration: TextDecoration.none,
fontWeight: FontWeight.normal,
),
),
),
color: Colors.green,
shape: new RoundedRectangleBorder(
borderRadius: new BorderRadius.circular(20.0)),
onPressed: () {
if(firstCondition && seacondCondition)
Navigator.push(context,
new MaterialPageRoute(builder: (context) => StartScanPage()));
else
Navigator.push(
context,
new MaterialPageRoute(
builder: (context) =>
StockInventoryPage(
userData['UserId'],
'${userDetail['Oid']}',
'${value['DistributionCentres'][i]['Oid']}',
stockoid)));
// Edit()was here
},
));
}
then simply put _showButton inside your children widget
