How to manage filesystem quota in Dart 1.5? -

-

in older versions of dart, there used function

window.storageinfo.requestquota(window.persistent, quota)

on top of that, there used function report:

queryusageandquota

i can see storageinfo class has been renamed deprecatedstorageinfo, , no longer available via window.storageinfo.

how can access functionality? quota exceeded errors, although increased value passed to:

window.requestfilesystem(quota, persistent: true)

it seems chrome in process of migrating w3c quota management api

see also

but seems has not yet landed in dartium.

the object returned 

window.navigator.storagequota

has no usable methods.
