Dynamically Updating TabController list at Runtime

Tags:

flutter

dart

I create a Pomodoro timer app use flutter. The home page has date TabController.

I record user first use the app date to a local JSON file. When the app starts checks the JSON file, and get the record. And calculate how many days between today, then I want to update tabcontroller.

The result is date correct, I set the initial index set the list.lenght - 1 but I set any number like 29,4,5,6, the underline is correct, but pageview is not right.

I think the problem is renewing tabController in setState, but I have tried many times it's not working.

Can someone help me see what went wrong? Thanks for the help.

I had code like this but not work. Dynamically Updating TabControl Content at Runtime

void initState() {
    super.initState();

    jsonFileHelper = new JsonFileHelper();

    myList.add(DateTime(today.year, today.month, today.day));
    tabController = new TabController(
      length: myList.length,
      vsync: this,
    );

jsonFileHelper.readToFile().then((res) {

        firstDate = DateTime.fromMillisecondsSinceEpoch(res['firstDate']);

        difference = DateTime(today.year, today.month, today.day)
            .difference(firstDate)
            .inDays;

        setState(() {
          myList.clear();
        });

        List<DateTime> tempList = new List();

        for (int i = 0; i <= difference; i++) {
          tempList.add(DateTime(today.year, today.month, today.day - i));
        }

        tempList.forEach((date) {
          myList.insert(0, date);
        });

        setState(() {
          tabController = new TabController(
              length: myList.length,
              vsync: this,
              initialIndex: myList.length - 1);

          tabController.addListener(() {
            animationController.reverse();
          });
        });
      }
    });
}

  // this is build tab function.
_buildTabs(List<DateTime> data) {
  List<Widget> listWidget = new List();

    data.forEach((date) {
      var widget = Container(
        child: Padding(
          padding: const EdgeInsets.all(8.0),
          child: Column(
            children: <Widget>[
              Text(DateFormat('EEE').format(date)),
              Text(
                date.day.toString(),
                style: TextStyle(
                  fontSize: 20.0,
                  color: Colors.black87,
                  fontWeight: FontWeight.bold,
                ),
              ),
            ],
          ),
        ),
      );
      listWidget.add(widget);
    });

    return listWidget;
  }

I expect the output is shown last day, but the actual output is 2019-03-01(I set the first record is 2019-2-28).
