how re-render component and why does onWeekChanged work when i click on day

[alperenkarip]

hi, i want to re-render calendar-strip when i change language of my app, but i failed. How do I re-render the calendar-strip when the app language changes? also how do I make onWeeksChanged work only when I click the right and left week buttons? I'm sorry for my bad english ?

I am not sure about re-render. Does it not automatically happen when the state changes?

On the second question about onWeekChanged being called, I can't seem to reproduce it.

I have the following strip:

                <CalendarStrip
                    scrollable={true}
                    startingDate={props.calendarStartDay}
                    selectedDate={props.calendarStartDay}
                    showMonth={false}
                    showDayName={false}
                    rightSelector={[]}
                    leftSelector={[]}
                    onWeekChanged={(start, end) => console.log(start, end)}
                    customDatesStyles={(date) => {
                        if (isDateSuccess(props.habitId, date)) {
                            return {
                                dateNameStyle: { color: 'blue' },
                                dateNumberStyle: { color: 'white' },
                                dateContainerStyle: { backgroundColor: 'green' },
                            }
                        }
                        return {};
                    }}
                    onDateSelected={(date) => updateHabitData(props.habitId, date)}
                // datesWhitelist={(date) => date.isBefore(today)} // TODO: UTC offset
                />

As you can see, I am printing a log if the week changes. That is not printed when I select a date. If I click on the Week shifters (left, right arrows in your case), only thne the log is printed.
