URL LAUNCHER not downloading any document

[Za7972]

Hello,

I´m using URL LAUNCHER in my application but everytime that I download one document, it doesn´t appear anything in my files.

1) I already gave permission to my app in android manifest

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.INTERNET" />

2) I already tested the same link directly in the phone browser and is working fine, so I guess there´s some problem with url launcher.

My code:

class _FuncionalidadesPageState extends State<FuncionalidadesPage> {
  Future<void> _launchURLFuncionalidadeEscolida(String url) async {
    if (await canLaunch(url)) {
      await launch(
        url,
        forceSafariVC: true,
        forceWebView: true,
        enableJavaScript: true,
      );
    } else {
      throw 'Não foi Possível abrir o Serviço $url, verifique seu dispositivo ou contate seu Município.';
    }
  }

Best Regards,

Are you sure url_launcher lets you download stuffs? I don't think you can do that with url_launcher. Probably you have to use a different plugin for that.

How does the code behave? Does the if-statement work as expected? Any exception?

I´ve found in internet this post:
https://stackoverflow.com/questions/56247542/how-to-download-create-pdf-through-webview-in-flutter/59899281#59899281

It is not working perfectly, it seens he start the download but when his going to save the file, flutter gives an exception (I´ve already changed the path but is still not working). 


If you guys can help me, i´ve prepared one github project with all the source code,just pub get and is ready to run.

Does the if-statement in canLaunch work as expected?

It works, the only problem is when we download any document using the webview component

To solve this problem I changed my code to forceWebView: FALSE;
