GFCarousel active page indicator is not being updated without "onPageChanged"

[yasalkhatib]

I noticed that the active page indicator is not being updated without explicitly call setState on onPageChanged callback.

Currently, if I need to update the active page indicator, I have to use GFCarousel inside a stateful widget and set onPageChanged,

onPageChanged: (index){
        setState(() {});
},

Hey @yasalkhatib, I solved this by wrapping it in my own StatefulWidget and calling setState(). This is a limitation they have. Something that I am trying to figures out now is how to actually start the indicators at the right "startingPageIndex" if I set an initialPage = 5, and I have 6 items, I want the dots to show active indicator at the end. However, it isn't doing this for me.

That's correct you, need to wrap it in a stateful widget and then call setState({}) on onPageChanged callback. However, I believe, this is a bug and for sure is not the intended behavior.

Regarding your question about "startingPageIndex". I faced the same problem. After reading the code, I found that the current implementation of GFCarousel doesn't take into consideration the initalPageIndex and always sets the dot index to 0.

Could you please open a separate issue and I will comment on it with a possible solution.

@yasalkhatib, sure. I created an issue here: #144
