paysheet 2.0.0+5

A lightweight, styling-only paysheet UI for Flutter.

paysheet

A lightweight, styling-only paysheet widget for Flutter apps. This package provides a minimal bottom-sheet paysheet UI intended for SDK / merchant integration where the host app handles payment interactions.

Features

• Stylized paysheet layout with merchant header and summary list
• Lightweight Paysheet.instance.present API
• Example app included

Quick example

await Paysheet.instance.present(
  context,
  method: 'card',
  amount: '9.99',
  onPay: () async {
    // call your server side integration here
  },
);

Styling & Widgets (_u)

paysheet exposes a lightweight UIAdjust configuration object that lets host apps customize the sheet's visual appearance and inject custom UI widgets into the paysheet body. The most common use is adding input controls such as a single-line card entry (card number, expiry, CVV) using the optional u parameter which accepts a List<Widget>.

Key UIAdjust fields:

• u : List<Widget>? — optional list of widgets to render inside the paysheet (rendered where the summary ends). Useful for custom inputs.
• backgroundColor : Color? — sheet background color (whitespace only).
• sheetCornerRadius : double? — corner radius for the header card.
• merchantHeaderColor, merchantHeaderElevation — header styling.
• buttonBackgroundColor, buttonForegroundColor, buttonTextStyle — pay button appearance.
• contentPadding : EdgeInsets? — outer padding for the sheet content.

The paysheet merges your UIAdjust with the package defaults via UIAdjust.defaults.merge(uiAdjust) so you only need to provide overrides.

Example: inject a single-line card field (card number | MM/YY | CVV)

await Paysheet.instance.present(
  context,
  method: 'card',
  amount: '1.00',
  uiAdjust: UIAdjust(u: [
    Padding(
      padding: const EdgeInsets.symmetric(vertical: 8.0),
      child: Container(
        padding: const EdgeInsets.symmetric(horizontal: 8.0, vertical: 6.0),
        decoration: BoxDecoration(
          color: Colors.white,
          borderRadius: BorderRadius.circular(8.0),
        ),
        child: Row(
          children: [
            Expanded(
              child: TextField(
                decoration: const InputDecoration(
                  isDense: true,
                  border: InputBorder.none,
                  hintText: 'Card number',
                ),
                keyboardType: TextInputType.number,
              ),
            ),
            const SizedBox(width: 8),
            SizedBox(
              width: 80,
              child: TextField(
                decoration: const InputDecoration(
                  isDense: true,
                  border: InputBorder.none,
                  hintText: 'MM/YY',
                ),
                keyboardType: TextInputType.datetime,
              ),
            ),
            const SizedBox(width: 8),
            SizedBox(
              width: 70,
              child: TextField(
                decoration: const InputDecoration(
                  isDense: true,
                  border: InputBorder.none,
                  hintText: 'CVV',
                ),
                keyboardType: TextInputType.number,
                obscureText: true,
              ),
            ),
          ],
        ),
      ),
    ),
  ]),
  onPay: () async {
    // perform your payment action
  },
);

Notes:

• Prefer white or neutral backgrounds for injected widgets to match the package's default look and avoid strong color clashes.
• The u widgets are placed after the summary and before the Pay button.
• If you need to programmatically read values from injected inputs, manage controllers or state within your own widgets and use the onPay callback to read them.
