Expandir imagen a nueva ventana

[JesusHdez960717]

Si se da un click en la imagen que se abra en una nueva ventana, con los mismos gesto de acercarse y demás, pero sin el teclado.

Usar un openContainer debe ser lo mas facil

//This method is used to build the image widget.
  //In this case using openContainer,
  //when the image is touched a new screen with the large image is displayed.
  _buildImageCard() {

      transitionType: ContainerTransitionType.fade,

      openColor: Colors.transparent,
      // The content that will be displayed when the widget opens.
      openBuilder: (context, _) => _buildBigImage(),
      closedElevation: 20,
      closedColor: Colors.transparent,
      // The content that will be displayed when the widget is closed.
      closedBuilder: (context, _) => _buildSmallImage(),
    );
  }

  //This method builds the image when is small.
  _buildSmallImage() {

        // Call the _fadeImage method for the fade effect.
        child: _fadeImage(controller.imageUrl),
