	// Signature format: 4.0
	package com.google.android.horologist.auth.sample.shared {
	public final class TokenSerializer implements androidx.datastore.core.Serializer<java.lang.String> {
	method public String getDefaultValue();
	method public suspend Object? readFrom(java.io.InputStream input, kotlin.coroutines.Continuation<? super java.lang.String>);
	method public suspend Object? writeTo(String t, java.io.OutputStream output, kotlin.coroutines.Continuation<? super kotlin.Unit>);
	property public String defaultValue;
	field public static final com.google.android.horologist.auth.sample.shared.TokenSerializer INSTANCE;
	}
	}

Things to check:

• metalava task doesn't seem to be available - was the plugin configuration removed?
• doesn't seem to be failing in CI, was the call to run it removed?

sample app should not have metalava config, this file will be removed in #1812
