Problem with ProGuard in custom view about viewbindingpropertydelegate

[alaegin]

@Anton111111 Try to add this rule to your proguard config.
It seems that the original distribution lucks of some rules.

-keep class * implements androidx.viewbinding.ViewBinding {
  public static *** bind(android.view.View);
  public static *** inflate(android.view.LayoutInflater);
  public static *** inflate(android.view.LayoutInflater, android.view.ViewGroup, boolean);
}

@alaegin , doesn't work with this rules too

@kirich1409 , @alaegin ,i've fixed my problem with small tuned of @alaegin advice.
I expanded the advice by adding a line: "public static *** inflate(android.view.LayoutInflater, android.view.ViewGroup);"

My complet proguard rule:

-keep class * implements androidx.viewbinding.ViewBinding {
public static *** bind(android.view.View);
public static *** inflate(android.view.LayoutInflater);
public static *** inflate(android.view.LayoutInflater, android.view.ViewGroup);
public static *** inflate(android.view.LayoutInflater, android.view.ViewGroup, boolean);
}

Will be fixed in 1.4.3

@kirich1409 , on last release (1.4.4) still doesn't works.
To fix it i remove "allowshrinking" from proguard rules.
