0.0.2

Maintenance release: clears the pub.dev analysis findings for a clean score.

Changed

• Upgraded fl_chart to ^1.2.0 and qr to ^4.0.0 (both now on their latest majors). The QR view adopts the qr 4.x QrPayload API.
• Raised the Flutter floor to >=3.44.0 and migrated every deprecated API to its current replacement: Switch activeColor to activeThumbColor, SemanticsService.announce to sendAnnouncement, SizeTransition.axisAlignment to alignment, Matrix4.scale to scaleByDouble, and DropdownButtonFormField.value to initialValue.

No public API changes; widgets render and behave exactly as before.

0.0.1

Initial public release: 140+ composable banking widgets across 22 domains, four built-in design languages, and one theming engine.

Components

• Accounts and balances, cards (virtual, physical, disposable, family), transactions, transfers and payments, savings and goals, social and joint accounts, investing, credit and lending, rewards, Islamic banking, onboarding and KYC, business banking, insights, notifications, support, and app gate and degraded states (maintenance, offline, force update, device and network security blocks, waiting room).
• Currency engine: 50+ currencies with correct symbols, minor units (3-decimal Gulf currencies, 0-decimal JPY and KRW, crypto precision), symbol placement, and bidi-isolated right-to-left symbols.
• Hijri (Umm al-Qura) calendar support with dual-calendar formatting.

Theming and design

• Four presets: Studio (default), Voltage, Bloom, and Heritage (Islamic-banking ready), each in light and dark.
• Custom theming: BankThemeData.custom() (only primary and brightness required) and the ThemeData.withBankTheme() extension.
• Every widget's colours, shapes, depth, text styles, icons, strings, and animation timing are overridable through optional constructor parameters that default to the theme.

Cross-cutting

• Privacy mode: BankBalanceText and every money surface mask through BankUiScope, verified by a mask-proof test across the render and semantics trees.
• First-class RTL across all widgets, with Western and Eastern Arabic-Indic numerals via NumeralStyle.
• BankUiStrings localization escape hatch; no gen-l10n dependency.
• Lossless Decimal-backed Money type; no double touches an amount.
• Headless flow controllers (BankKycFlowController, BankTransferFlowController, BankIncomeSorterController) that never touch the network.

Quality

• flutter analyze clean on the package and the example app.
• Unit and widget tests across presets, both brightnesses, and RTL.
• Semantics on every control and 44 px minimum touch targets.
• Interactive component gallery and a full demo dashboard in example/.
