📦 jbdev (Internal Utility Package) #

A collection of extensions, widgets, and helpers to streamline JBDEV app development. Maintained by Jatin Batra — not for public use.

🔧 Core Setup #

Wrap your app:

App.init();
runApp(Jbdev(
  builder: (ctx, navKey) => MaterialApp(navigatorKey: navKey, home: HomePage()),
));

Quick config:

App.currencySymbol = "₹";
App.locale = JBLocale.en_IN;
App.timezone = JBTimezone.ist;

⚙️ JBConfig Settings #

Customize:

• Default button styles
• Popup / BottomSheet UI
• Locale, timezone, symbol

Override widgets:

JBConfig.defCurrencySymbol = '₹';
JBConfig.defLocale = JBLocale.en_IN;
JBConfig.defTimezone = JBTimezone.ist;

JBConfig.loadingPopupWidget = (ctx) => MyCustomLoading();
JBConfig.popupWidget = (ctx, popup) => MyCustomPopup(popup);
JBConfig.bottomSheetWidget = (ctx, popup) => MyBottomSheet(popup);

JBConfig.bottomSheetMaxHeight = 0.8;
JBConfig.bottomSheetBorderRadius = 16;
JBConfig.bottomSheetBackgroundColor = Colors.white;
JBConfig.bottomSheetBarrierBlur = 4;

JBConfig.popupBarrierColor = Colors.black54;
JBConfig.popupBorderRadius = 16;
JBConfig.popupPadding = EdgeInsets.all(26);
JBConfig.popupBarrierBlur = 4;
JBConfig.popupBackgroundColor = Colors.white;

JBConfig.defaultButton = JBButtonProperties(
color: Colors.blue,
textColor: Colors.white,
);

JBConfig.buttons = {
"success": JBButtonProperties(color: Colors.green, textColor: Colors.white),
"error": JBButtonProperties(color: Colors.red, textColor: Colors.white),
"primary:light": JBButtonProperties(color: Colors.blue.shade100, textColor: Colors.black),
// Add more types as needed
};
