### Changes
* Introduces a new `viewConstraints` JS configuration parameter to configure max/min width/height constraints for a view. Those can have the following values:
* An integer `>= 0`: max/min size in pixels
* `Infinity` (or `Number.POSITIVE_INFINITY`): (only for max values) -> **unconstrained**.
* When any value is not set, it defaults to "tight to the current size".
* See [Understanding constraints](https://docs.flutter.dev/ui/layout/constraints).
* Computes the correct `physicalConstraints` of a view off of its `physicalSize` and its `viewConstraints` for the framework to use during layout.
* When no constraints are passed, the current behavior is preserved: the default constraints are "tight" to the `physicalSize`.
* Resizes the current view DOM when requested by the framework and updates its internal physicalSize, then continues with the render procedure.
### Example
This is how we can configure a view to "take as much vertical space as needed":
```js
flutterApp.addView({
viewConstraints: {
minHeight: 0,
maxHeight: Infinity,
},
hostElement: ...,
});
```
