I have cloned your project but i can not start it .I got this error:

ERROR: path may not be null or empty string. path='null'
Open File

This error is related to this section :

       release {
           keyAlias keystoreProperties['keyAlias']
           keyPassword keystoreProperties['keyPassword']
           storeFile file(keystoreProperties['storeFile'])
           storePassword keystoreProperties['storePassword']
       }

I cant seem to resolve the new TextTheme elements(headline3, headline4 etc).

I see it in the flutter master branch but it doesnt seem to resolve locally even on upgrading all the dependencies. Is this still not a part of flutter's stable branch?

Hi, your app looks great!

After I changed the currency to Euro, it's correctly listed on the start screen but in the tab view and when adding a tab it still shows $

Users should be able to select from common currencies (USD, CAD, GBP, EUR, etc...). Alternatively they can enter (max 4 characters) currency using the keyboard.
