Added #

• Torch button position control with torchButtonPosition parameter
• Four position options: topLeft, topRight, bottomLeft, bottomRight (default)
• TorchButtonPosition enum for type-safe position selection

Added #

• Smart border coloring: borderColor parameter now nullable for auto-color mode
• When borderColor is null, QR codes with same value get same color
• Added visual examples in README showing both color modes

Fixed #

• QR code border colors now properly respect the borderColor parameter
• Fixed random color generation that was overriding user-specified border colors

Added #

• Automatic runtime camera permission handling on Android
• Camera permissions are now requested automatically by the plugin when needed
• No manual AndroidManifest.xml permission setup required

  • TorchMode.off: Torch always off
  • TorchMode.auto: Automatically turns on in low light (< 10 lux)

• Light sensor integration for automatic torch control
• Customizable torch button colors
