'Invariant Violation' error when using the panel

[moisesynfam]

Issue Description

I get this error when using the panel. It happens on the view not even with the panel showing. All it says is "Invariant Violation: Invariant Violation: inputRange must be monotonically non - decreasing 0, NaN"

Steps to Reproduce / Code Snippets / Screenshots

I only specified the backdropOpacity and the allowDragging props. I did notice when I didn't specify other props like draggableRange, the top value was set to NaN and not defaulted to 0. I think that is why the _renderBackdrop() function is throwing the error.

<SlidingUpPanel
                ref={ ref => this._panel = ref}
                allowDragging={false}
                backdropOpacity={0.25}
            > ... </SlidingUpPanel>

Thanks for reporting the issue. Can you console.log the Dimensions.get('window') and StatusBar.currentHeight? The top of draggableRange is actually calculated base on these values.

Similar problem here when dragging the panel for open it (only sometimes).

Malformed calls from JS: field sizes are different.

[[38,9,52,52,52,52,52,52,52],[6,1,3,3,3,3,3,3,0],[["[163,\"RCTView\",{\"opacity\":\"<<NaN>>\"}] is not usable as a native method argument"

with these panel props:

<SlidingUpPanel
        backdropOpacity={0.4}
        snappingPoints={[this._draggableRange.bottom, this._draggableRange.top]}
        animatedValue={this._animatedValue}
        ref={c => (this._panel = c)}
        friction={0.5}
        draggableRange={this._draggableRange}

mmm... I have a TouchableWithoutFeedback inside the content panel and I see that the exception is raised when I start dragging touching the touchable.
