resolveTursoSharedConfig function

TursoSharedConfig resolveTursoSharedConfig({ required Map shared, required String appName, FlavorContext? flavorContext, })

Resolves cloudflare.turso.shared from shared.

Values may be a {dev:, prod:} map or a single value. Empty values use the defaults (<app>-dev-shared / <app>-shared, groups <app>-dev / <app>-us) where <app> is appName (the pubspec name with _ replaced by -). Throws FormatException for invalid values.

sharedからcloudflare.turso.sharedを解決します。

値は{dev:, prod:}形式または単一値で指定できます。空の場合は既定値 （<app>-dev-shared / <app>-shared、group <app>-dev / <app>-us）を使います。 <app>はappName（pubspecのnameの_を-に置換したもの）です。 不正な値はFormatExceptionを投げます。
