BottomSheetBehavior Illegal state argument: 5

Could someone explain about when this exception occurs?

As @Serj Ardovic explain it s the Hideable

I wanted to add that you can also put it in the xml :

<androidx.constraintlayout.widget.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="@+id/bottom_sheet"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:behavior_hideable="true"   <- this here
app:layout_behavior="com.google.android.material.bottomsheet.BottomSheetBehavior">

For me problem was resolved by sheetBehavior.setHideable(true); It seems when setHideable is false and then setting state to BottomSheetBehavior.STATE_HIDDEN exception will occurred

public class IllegalArgumentException extends RuntimeException

Thrown to indicate that a method has been passed an illegal or inappropriate argument.

Somewhere in your code, you are passing an illegal argument to the method startSettlingAnimation() (BottomSheetBehavior class). This method is throwing the exception:

void startSettlingAnimation(View child, int state) {
    int top;
    if (state == STATE_COLLAPSED) {
      top = mCollapsedOffset;
    } else if (state == STATE_HALF_EXPANDED) {
      top = mHalfExpandedOffset;
    } else if (state == STATE_EXPANDED) {
      top = getExpandedOffset();
    } else if (mHideable && state == STATE_HIDDEN) {
      top = mParentHeight;
    } else {
      throw new IllegalArgumentException("Illegal state argument: " + state);
    }
    if (mViewDragHelper.smoothSlideViewTo(child, child.getLeft(), top)) {
      setStateInternal(STATE_SETTLING);
      ViewCompat.postOnAnimation(child, new SettleRunnable(child, state));
    } else {
      setStateInternal(state);
    }
  }

Your error is: Illegal state argument: 5. 5 is the int value of STATE_HIDDEN. So while your state is STATE_HIDDEN (5), your mHideable boolean is false. So, the basic suggestion would be to set the mHideable = true;

Without any code, that's as much as I can tell you.
