SetState not changing the preview, is this even possible?

[Luppakorva]

Thank you for the plugin!

Could you possibly let me know if it's possible to change the url in setstate?

When I try to do this absolutely nothing happens when url is changed and setstate launched.

What I got as an example:

  String previewUrl = 'https://google.com';


Widget build(BuildContext context) {
 

    PostsViewModel viewModel = Provider.of<PostsViewModel>(context);
    return WillPopScope(
      onWillPop: () async {
        await viewModel.resetPost();
        return true;
      },
      child: ModalProgressHUD(
        progressIndicator: circularProgress(context),
        inAsyncCall: viewModel.loading,
        child: Scaffold(
          key: viewModel.scaffoldKey,
          appBar: AppBar(
            leading: IconButton(
              icon: Icon(Feather.x),
              onPressed: () {
                viewModel.resetPost();
                Navigator.pop(context);
              },
            ),
            title: Text('MyApp'),
            centerTitle: true,
            actions: [
              InkWell(
                onTap: () async {
                  print(controller.text);
                  await postToApi(viewModel.description);
                  controller.clear();
                  viewModel.resetPost();

                  Navigator.pushReplacement(
                    context,
                    MaterialPageRoute(builder: (context) => TabScreen()),
                  );
                },
                child: Padding(
                  padding: const EdgeInsets.all(20.0),
                  child: Text(
                    'Post'.toUpperCase(),
                    style: TextStyle(
                      fontWeight: FontWeight.bold,
                      fontSize: 15.0,
                      color: Theme.of(context).accentColor,
                    ),
                  ),
                ),
              )
            ],
          ),
          body: ListView(
            children: [

              AnyLinkPreview(
                link: previewUrl,
                displayDirection: UIDirection.UIDirectionHorizontal,
                cache: Duration(hours: 1),
                backgroundColor: Colors.grey[300],
                errorWidget: Container(
                  color: Colors.grey[300],
                  child: Container(),
                ),
              ),
Padding(
                padding: EdgeInsets.all(10),
                child: Column(children: [
                  Container(
                    width: double.infinity,
                    child: Text(
                      'Link'.toUpperCase(),
                      style: TextStyle(
                        fontSize: 15.0,
                        fontWeight: FontWeight.w600,
                      ),
                    ),
                  ),
                  TextFormField(
                    decoration: InputDecoration(
                      hintText: 'Source',
                      focusedBorder: UnderlineInputBorder(),
                    ),
                    maxLines: null,
                    onChanged: (value) {
                      _url1 = value;
                      previewUrl = value;

                    },
                  ),
                  TextButton(
                    child: Text("Fetch"),
                    onPressed:() {
                      setState(() {
                        print(previewUrl);
                      });
                    },
                  )
                ]),
              ),
]);

However this does not refresh the preview even though previewURL changes with setState. Any way to achieve this?

Running the latest RC as version.

Hey,

It's not recommended to use setState() inside the TextField's onChange method. Instead you can use Debouncer() to achieve the refresh.

However, I have verified the same locally & seems it is refreshing the link preview card.
Feel free to open the new issue if the issue persists.

Thanks!
