Web build wont load, something to do with material icons fonts otf file?

[cyberpwnn]

Steps to Reproduce

1. Run flutter build web (any variant of release mode or debug with optimizations at -O0 to -O4 doesnt matter)
2. Observe the error when loading the page (im using firebase hosting)

Expected results:
It works as expected

Actual results:
Page never loads, with the error in the chrome console

Uncaught TypeError: J.getInterceptor$ax(...).clear$0 is not a function
    at Object.clear$0$ax (main.dart.js:121591:44)
    at main.dart.js:4420:17
    at _wrapJsFunctionForAsync_closure.$protected (main.dart.js:15283:15)

    at _wrapJsFunctionForAsync_closure.call$2 (main.dart.js:153961:12)
    at Object._asyncStartSync (main.dart.js:15248:20)

The source code for _downloadAssetFonts is

_downloadAssetFonts() {
      var $async$goto = 0,
        $async$completer = A._makeAsyncAwaitCompleter(type$.void),
        t1, t2;
      var $async$_downloadAssetFonts = A._wrapJsFunctionForAsync(function($async$errorCode, $async$result) {
        if ($async$errorCode === 1)
          return A._asyncRethrow($async$result, $async$completer);
        while (true)
          switch ($async$goto) {
            case 0:
              // Function start
              J.clear$0$ax(A.renderer().get$fontCollection());
              $async$goto = $._assetManager != null ? 2 : 3;
              break;
            case 2:
              // then
              t1 = A.renderer().get$fontCollection();
              t2 = $._assetManager;
              t2.toString;
              $async$goto = 4;
              return A._asyncAwait(t1.downloadAssetFonts$1(t2), $async$_downloadAssetFonts);
            case 4:
              // returning from await.
            case 3:
              // join
              $async$goto = A.boolConversionCheck(A.debugEmulateFlutterTesterEnvironment()) ? 5 : 6;
              break;
            case 5:
              // then
              $async$goto = 7;
              return A._asyncAwait(A.renderer().get$fontCollection().debugDownloadTestFonts$0(), $async$_downloadAssetFonts);
            case 7:
              // returning from await.
            case 6:
              // join
              // implicit return
              return A._asyncReturn(null, $async$completer);
          }
      });
      return A._asyncStartSync($async$_downloadAssetFonts, $async$completer); // FAILS RIGHT HERE
    },

Looking at it, i think here J.clear$0$ax(A.renderer().get$fontCollection()); It's complaining that fontCollection() is not a function? This happened while upgrading flutter but downgrading doesnt seem to fix it or at least i cant recover it to a working state, I also tried flutter channel beta but there are issues with that also.

Thanks for the report @cyberpwnn
I tried the same scenario on a sample app using latest master which first gave me below in console upon running flutter build web:

dhs@Dhss-MacBook-Pro test_app % flutter build web

Font asset "CupertinoIcons.ttf" was tree-shaken, reducing it from 283452 to 1236 bytes (99.6% reduction). Tree-shaking can be disabled by providing the --no-tree-shake-icons flag when
building your app.
Font asset "MaterialIcons-Regular.otf" was tree-shaken, reducing it from 1645184 to 7548 bytes (99.5% reduction). Tree-shaking can be disabled by providing the --no-tree-shake-icons flag
when building your app.
Compiling lib/main.dart for the Web...                             29.8s

Although I didn't try hosting on any external server, upon running on localhost, it worked properly without giving the reported error:

If you could provide us exact steps to replicate, it'll help to properly analyze the issue. Or you may also try on latest master to see if it persists or not.

Without additional information, we are unfortunately not sure how to resolve this issue. We are therefore reluctantly going to close this bug for now.
If you find this problem please file a new issue with the same description, what happens, logs and the output of 'flutter doctor -v'. All system setups can be slightly different so it's always better to open new issues and reference the related ones.
Thanks for your contribution.
