Tiled's infinite mode will report an error

[zhou26192619]

What happened?

mapComponent = await TiledComponent.load('map.tmx', Vector2(32.0, 32.0));
I just need to change the tiled mode to infinite, and there will be an error：

The following TypeErrorImpl was thrown building FutureBuilder<void>(dirty, state: _FutureBuilderState<void>#b0632):
Unexpected null value.

The relevant error-causing widget was: 
 FutureBuilder<void> FutureBuilder:file:///C:/Users/46089/AppData/Local/Pub/Cache/hosted/pub.flutter-io.cn/flame-1.37.0/lib/src/game/game_widget/game_widget.dart:418:30

Afaik we don't have support for Tiled's infinite mode yet, so changing this to a feature request.
My guess is that some work probably has to be done in https://github.com/flame-engine/tiled.dart too.
