I am trying to use TextFlow coming from FXML but no text is shown.

I have tried:

textflow.getChildren.add(text);

and also:

textflow=new TextFlow(text);

where text is:

Text text=new Text("AAA");

I both cases TextFlow shows nothing.

Is there another container for use with rich text using FXML JavaFX app?

For sure if I try both cases in non-FXML JavaFX app it works both of them.

In your controller class inside the initialize method you are loosing the reference to the old txtF object declared in your FXML by instantiating a new TextFlow object with the same name, and you are not adding this new object to your AnchorPane. So you'll need to remove this line txtF=new TextFlow(new Text("aaa"));

If you would like assistance with this, you should provide an mcve.

Maybe but I could not agree.

FXML

    <?xml version="1.0" encoding="UTF-8"?>

    <?import java.lang.*?>
    <?import java.util.*?>
    <?import javafx.scene.*?>
    <?import javafx.scene.control.*?>
    <?import javafx.scene.layout.*?>
    <?import javafx.scene.text.TextFlow?>

    <AnchorPane id="AnchorPane" prefHeight="200" prefWidth="320" xmlns:fx="http://javafx.com/fxml/1" fx:controller="testfxmlpackage.FXMLDocumentController">
        <children>
            <TextFlow fx:id="txtF" layoutX="22.0" layoutY="234.0" prefHeight="74.0" prefWidth="433.0" style="-fx-border-color: ADD8E6;" AnchorPane.bottomAnchor="14.0" AnchorPane.leftAnchor="22.0" AnchorPane.rightAnchor="142.0" />              
        </children>
    </AnchorPane>

Controller

    package testfxmlpackage;

    import java.net.URL;
    import java.util.ResourceBundle;
    import javafx.fxml.FXML;
    import javafx.fxml.Initializable;
    import javafx.scene.text.Text;
    import javafx.scene.text.TextFlow;

    public class FXMLDocumentController implements Initializable { 
       
      @FXML TextFlow txtF; 
       
      @Override
      public void initialize(URL url, ResourceBundle rb) {
        txtF=new TextFlow(new Text("aaa"));
        txtF.getChildren().add(new Text("aaa"));
      }   
    }

Main Class

    package testfxmlpackage;

    import javafx.application.Application;
    import javafx.fxml.FXMLLoader;
    import javafx.scene.Parent;
    import javafx.scene.Scene;
    import javafx.stage.Stage;

    public class TestFXMLPackage extends Application {
 
      @Override
      public void start(Stage stage) throws Exception {
        Parent root = FXMLLoader.load(getClass().getResource("FXMLDocument.fxml"));
   
        Scene scene = new Scene(root);
   
        stage.setScene(scene);
        stage.show();
      }

      public static void main(String[] args) {
        launch(args);
      } 
    }
