【注意】Flutter 1.24 FlutterMain被废弃了的替代方案|flutterAssetsDir on a null

Flutter 1.24 FlutterMain被废弃了，用FlutterMain.findAppBundlePath()换成HiFlutterLoader.get()，同时也能fix:

java.lang.NullPointerException: Attempt to read from field 'java.lang.String io.flutter.embedding.engine.loader.FlutterApplicationInfo.flutterAssetsDir' on a null object reference

将：

flutterEngine.dartExecutor.executeDartEntrypoint(
    DartEntrypoint(
        FlutterMain.findAppBundlePath(),
        moduleName
    )
)

修改为：

flutterEngine.dartExecutor.executeDartEntrypoint(
    //  Flutter 1.24 FlutterMain被废弃了，用FlutterMain.findAppBundlePath()换成HiFlutterLoader.get()
    //  ，以fix java.lang.NullPointerException: Attempt to read from field 'java.lang.String io.flutter.embedding.engine.loader.FlutterApplicationInfo.flutterAssetsDir' on a null object reference
    DartEntrypoint(
        HiFlutterLoader.get().findAppBundlePath(),
        moduleName
    )
)
