app_snackbar

✨ New Features

Per-call Icon Override

• icon param added to show(), success(), error(), warning(), info(), showWithAction(), showLoading()
• Priority chain: per-call icon → AppSnackBarTheme icon → built-in default
• Example: AppSnackBar.success(context, 'Done!', icon: Icons.cloud_done_rounded)

Action Icon in showWithAction()

• actionIcon — optional icon shown left of the action button label
• If null, only the label text is shown (no breaking change)
• Example: AppSnackBar.showWithAction(context, 'Deleted', actionLabel: 'UNDO', actionIcon: Icons.undo_rounded, onAction: restore)

Custom Progress Indicator in showLoading()

• progressIndicator — pass any widget (CircularProgressIndicator, LinearProgressIndicator, Lottie, etc.)
• Falls back to default white CircularProgressIndicator if not provided
• Example: AppSnackBar.showLoading(context, 'Uploading...', progressIndicator: LinearProgressIndicator())

Per-call Queue Override

• useQueue param added to all public methods
• Priority chain: per-call useQueue → AppSnackBar.useQueue (global)
• Example: AppSnackBar.error(context, 'Critical!', useQueue: false)

Top Position Fix

• SnackBarPosition.top now correctly renders at the top on all devices
• Root cause: ScaffoldMessenger always renders at bottom regardless of margin
• Fix: top position now always forces overlay mode, bypassing ScaffoldMessenger entirely

✨ Documentation Fix

• Fixed: screenshots not showing on pub.dev — replaced HTML <img> tags with GitHub raw URLs

✨ New Features

Timer Bar

• showTimer — shows a countdown progress bar at the bottom of the snackbar
• timerColor — customize the timer bar color per-call
• AppSnackBarTheme.showTimer — enable timer globally for all snackbars
• AppSnackBarTheme.timerColor — set default timer bar color in theme

Duration Control

• AppSnackBarTheme.defaultDuration — set a global default duration once in theme
• Per-call duration always takes priority over theme default
• Fallback chain: per-call → theme default → built-in default (3s)

🐛 Bug Fix

• Fixed: showing a new snackbar while one was already visible caused the old one to be abruptly removed at the same time, resulting in both dismissing together — now the old snackbar cleanly finishes before the new one appears
