Best practices for internationalization (i18n) and localization (l10n) in Flutter, using the built-in \`flutter\_localizations\` and \`intl\` setup with ARB files as the single source of truth. Use when adding, modifying, or reviewing ARB translations, locale setup (\`l10n.yaml\`, \`generate: true\` in \`pubspec.yaml\`, \`flutter gen-l10n\`, \`localizationsDelegates\`, \`supportedLocales\`), BuildContext l10n extensions such as \`context.l10n\`, hardcoded user-facing strings that should be localized, localized strings passed into shared or reusable widgets, or RTL/directional layout support with \`EdgeInsetsDirectional\`. Also use when asked to add or configure any third-party i18n or translation package (easy\_localization, slang, flutter\_i18n, or intl\_utils), and when shipping or fixing a screen for a right-to-left language such as Arabic, Hebrew, Farsi, or Urdu, including mirroring padding, alignment, icons, or images, and replacing \`EdgeInsets\` left/right.
