Why my variable is null

Development Programming & Scripting C++

I have a class Act_31 and from it I want to call function, which change the text inside widget.
There is a virtual function NativeConstruct(), which calls automatically. And it change text of widget, but I need to call function F1 and send text to it, which I want to display. But when I call it, variable Name is null.
And by some reason it is not null, when program call NativeConstruct().

From here I call function from another class

void AAct_31::BeginPlay()
{
	Super::BeginPlay();
	
	UAccessWidgetFromCpp* accessWidgetFromCpp = NewObject<UAccessWidgetFromCpp>();
	accessWidgetFromCpp->F1("222");
	widgetDialogBottomInstance->AddToViewport();
}

.h

UCLASS()
class HOME_API UAccessWidgetFromCpp : public UUserWidget
{
	GENERATED_BODY()
	
public:
	UPROPERTY(BlueprintReadOnly, meta = (BindWidget))
	class UTextBlock* Name;

	UFUNCTION()
	virtual void NativeConstruct() override;

	UFUNCTION()
	void F1(FString text);
};

.cpp

#include "AccessWidgetFromCpp.h"

void UAccessWidgetFromCpp::NativeConstruct()
{
	if (Name) // Name not null
	{
		Name = (UTextBlock*)GetWidgetFromName(TEXT("Name"));
		Name->SetText(FText::FromString("111"));
	}
}

void UAccessWidgetFromCpp::F1(FString text)
{
	if (Name) //Error: Name is null
	{
		Name = (UTextBlock*)GetWidgetFromName(TEXT("Name"));
		Name->SetText(FText::FromString(text));
	}
}

You should never create widgets using NewObject. (I really wish it would complain :D)

UAccessWidgetFromCpp* AccessWidgetFromCpp  = CreateWidget<UAccessWidgetFromCpp>(GetWorld()->GetFirstPlayerController(), UAccessWidgetFromCpp::StaticClass());

if (AccessWidgetFromCpp)
{
     AccessWidgetFromCpp->F1("222");
     AccessWidgetFromCpp->AddToViewport();
}

Thank you, I did it. But still when I call my functuon F1, variable Name is null, and with function NativeConstruct it is not null

@dimakozyr, I got the same problem and am wondering if you find any solution for this?
