This looks great overall. However, we need to consider the issue #1979 . Previously, the sdk did not care about mismatch between state and config after a terraform action was performed but with this change, it will exit with Provider produced inconsistent result after apply.

I think the best approach here is to modify the updateState methods to always use whatever the user supplied. Something like:

func (r *dashboardListResource) updateStateFromResponse(ctx context.Context, state *dashboardListResourceModel, dashboards []datadogV2.DashboardListItemResponse) {
	temp := []*DashItemModel{}
	for _, dashboard := range dashboards {
		dashboardItem := DashItemModel{}
		dashboardItem.Dash_id = types.StringValue(dashboard.GetId())

		found := false
		for _, v := range state.DashItem {
			if v.Dash_id.ValueString() == dashboard.GetId() {
				dashboardItem.Type = v.Type
				found = true
			}
		}
		if !found {
			dashboardItem.Type = types.StringValue(string(dashboard.GetType()))
		}

		temp = append(temp, &dashboardItem)
	}
	state.DashItem = temp
}
