      1. Create an ItemStack and set some boolean-like String value (e.g. testplugin:value: 'TRUE')
      2. Serialize it to YAML (the code below also saves it to a file because it's its main purpose)
      3. Deserizlize the ItemStack from the output code and the value has become 1b
      public void onEnable() {
    File saveFile = new File(getDataFolder(), "test.yml");
    
    try {
        FileConfiguration configuration = new YamlConfiguration();
        ItemStack item = new ItemStack(Material.STONE);
        ItemMeta meta = item.getItemMeta();
        meta.getPersistentDataContainer().set(new NamespacedKey(this, "value"), PersistentDataType.STRING, "TRUE");
        item.setItemMeta(meta);
        configuration.set("item", item);
        configuration.save(saveFile);

        // SAVED
        getLogger().info(configuration.saveToString());

    } catch (IOException e) {
        e.printStackTrace();
    }

    try {
        FileConfiguration configuration = new YamlConfiguration();
        configuration.load(saveFile);

        // LOADED
        getLogger().info(configuration.saveToString());

    } catch (IOException | InvalidConfigurationException e) {
        e.printStackTrace();
    }
}
