delays in rendering a page for appintroslider when app is first opened in version 4.0.4

[nketia]

I upgraded the package to the current version 4.0.4 from 2.0.1 and this seems to be causing delays when rendering for the first time. Navigating to the page for appintroslider drags for about 5 seconds before it opens. This used not to be the case and behaves normally when I downgrade to the 2.0.1

after delving into the source code,
i saw

// index.js
this.state = {
      width: 0,
      height: 0,
      activeIndex: 0,
  };

i change this value width and height to

// Dimensions is from react-native
this.state = {
            width: Dimensions.get('screen').width,
            height: Dimensions.get('screen').height,
            activeIndex: 0,
        };

so the slider wont have width 0 at first (before, seemingly there is no slide at first)

is that what you mean with render time? this is what i meant

I faced the same issue and patched by setting the width and height using Dimensions. Otherwise your slides can may "glitch" initially before the onLayout event is called on the FlatList.
