# Viewport Dialog Provider

This is a context provider that allow the application to share the modal
component across all application.

## Sample

<Playground>
  {() => {
    const ViewportNotification = ({ hide }) => {
      return (
        <Notification
          message="Track all measurement for this series?"
          type="info"
          actions={[
            {
              type: 'cancel',
              text: 'No',
              value: 0,
            },
            {
              type: 'secondary',
              text: 'No, do not ask again',
              value: -1,
            },
            {
              type: 'primary',
              text: 'Yes',
              value: 1,
            },
          ]}
          onSubmit={value => { window.alert(value); }}
        />
      );
    };
    const ViewportActionButtons = () => {
      const dialog = useViewportDialog();
      return (
        <Button
          onClick={() =>
            dialog.show({
              content: ViewportNotification,
            })
          }
        >
          Open Dialog
        </Button>
      );
    };
    return (
      <div className="w-full flex flex-row p-4" style={{height: '400px'}}>
        <div className="flex flex-1 items-center justify-center h-full w-full bg-black text-white border border-primary-main">
          <ViewportDialogProvider dialog={Dialog}>
            <div className="flex flex-1 flex-col items-center justify-center h-full">
              <ViewportActionButtons />
              <span>CONTENT 1</span>
            </div>
          </ViewportDialogProvider>
        </div>
        <div className="flex flex-1 items-center justify-center h-full w-full bg-black text-white border border-primary-main">
          <ViewportDialogProvider dialog={Dialog}>
            <div className="flex flex-1 flex-col items-center justify-center h-full">
              <ViewportActionButtons />
              <span>CONTENT 1</span>
            </div>
          </ViewportDialogProvider>
        </div>
      </div>

          actions={[
            {
              type: 'cancel',
              text: 'No',
              value: 0,
            },
            {

          ]}
          onSubmit={value => { window.alert(value); }}
        />
      );
    };
    // Creating servicesManager and register services should be in the root of your app
    const servicesManager = new ServicesManager();
    servicesManager.registerServices([UIViewportDialogService]);
    // Get service instance
    const _UIViewportDialogService =
      servicesManager.services.UIViewportDialogService;

          >
            Open dialog on 1

        </div>
        <div className="flex flex-1 w-full flex-row">
          <ViewportDialogProvider
