About google_sheet_localize

Creates .strings files for iOS and strings.xml files for Android

to use our plugin you have to duplicate this google sheet: Example

Google Drive access token: Guide

  • The language_titles (the columns which should be exported)
  • The default_language (If a string is not present in a specific language, this is the fallback)
  • The base_language (The language which is placed in the base values folder)

Sheet Language

Arguments: (Android + iOS + Web)

English: Mario ate a %2s %1s.
German: Mario hat %1s einen %2s gegessen.

In this case %2s stands for Apple and %1s for Today, the order is different in this example, so we need to take care of it.

Mapped iOS: Mario ate a %2$@ %1$@.
Mapped Android: Mario ate a %2s %1s.
Mapped Web: Mario ate a {2} {1}.

Plurals: (Android + iOS)

one|%d artist
other|%d artists

String Array: (Android)

["Monday", "Tuesday", "Wednesday"]

iOS specifics

In order to support Objective-C, the plugin provides the support_objc argument, which is default false.
Therefore, if you need Objective-C support pass support_objc: true.
