Hi, this package is assuming 150ppi on Android/iOS devices.
Where does this come from? It seems not very accurate.

Amazing package!

Just for curiosity, is there any possibility of decreasing performance using that package?

Hey there,
When using context.widthPx, where is that size actually coming from? I am trying to put an AnimatedContainer inside my Expanded widget, as I am using an event to resize two Expanded containers on three possible conditions. Both start off at 50/50 flex size, then on the second condition it changes to 25/75, the last condition it's 75/25. It worked well without the Animated container, but the size transition is instant and I would prefer to have it animate.

I was hoping that this package might be able to help somehow, but I am not quite sure where the size of context.widthPx is coming from? Is it the size of wherever it happens to be in the widget tree at the time it is being called, the size of the topmost parent of that particular widget up to the most recent build method, or is it the size of the screen itself?

This is essentially how things are setup at the moment:

  Flex(
    direction: Axis.horizontal,
    crossAxisAlignment: CrossAxisAlignment.end,
    children: <Widget>[
      Expanded(  // <---  I would like to get the current width of this
        flex: (target[expController.target]["newsWidth"]),
        child: AnimatedContainer(
          width: ?, // <-- and use it here
          duration: Duration(milliseconds: 500),
          curve: Curves.fastOutSlowIn,
          child: NewsMainHome(),
        ),
      ),
      Spacer(flex: target[expController.target]["spacer"]),
      Expanded(
        flex: (target[expController.target]["changeLogWidth"]),
        child: AnimatedContainer(
          width: ?, // Set to parent size
          duration: Duration(milliseconds: 500),
          curve: Curves.fastOutSlowIn,
          child: ChangeLogList(),
        ),
      ),
    ],
  ),

It would be nice to be able to set the AnimatedContainer width to the size of the parent Expanded width so it will animate the size transition when the Expanded flex value changes from the event, but I have yet to find a decent way to go about it.

Thanks,

I think line 44:
double get diagonalInches => diagonalPx / 96;

Should be:
double get diagonalInches => diagonalPx / pixelsPerInch;

In Flutter 3.10, new media query methods are introduced.
Such as MediaQuery.sizeOf and MediaQuery.devicePixelRatioOf, using these methods instead of accessing MediaQuery.of(context) directly could potentially improve performance.
