antinvestor_ui_ledger

Embeddable Flutter screens, widgets, and Riverpod providers for the Antinvestor double-entry ledger service. Drops into any host app via LedgerRouteModule — registers the routes, nav items and permission manifest with no host glue required.

Backend it talks to

Configured via the compile-time env variable LEDGER_URL:

flutter run --dart-define LEDGER_URL=https://ledger.your.cluster

Auth follows the host app's authTokenProviderProvider from antinvestor_ui_core.

Screen index

/ledger/ledgers — Chart of accounts

The ledger hierarchy. Each row shows id, type, parent ledger, and a 3-key data preview. Type filter narrows by Asset / Liability / Income / Expense / Capital.

Action: "New ledger" opens a modal. Required: name, type. Optional: parent ledger id (for hierarchical nesting), default currency — name and currency are carried in the ledger's free-form data struct.

Permissions: ledger_view. Manage permission is ledger_create.

/ledger/ledgers/:id — Ledger detail

Two tabs:

• Info: identity, type badge, parent reference, metadata.
• Accounts: scrollable list of accounts in this ledger with their balance / uncleared / reserved tiles.

/ledger/accounts — Account list

Free-text search + standard list table. Columns: id, ledger, balance, uncleared, reserved.

/ledger/accounts/:id — Account detail

Balance card on top, transaction history below. Running balance is shown per entry. From here, navigate into:

/ledger/accounts/:id/statement — Account statement

The customer-facing statement screen. Filter by date range (RFC3339), view opening + closing balances, per-side totals, and the chronological entry list with running balance per row.

Export in the app bar: CSV / Excel / PDF. Filename pattern: statement_<accountID>_<UTC stamp>.<ext>.

Permissions: report_view.

/ledger/transactions — Transaction list

Most-recently-transacted first by default. Columns: id, currency, type badge, transacted-at, entry count, cleared indicator.

/ledger/transactions/:id — Transaction detail

Entry count headline, type + currency badges, ID and timestamp. Below: list of TransactionEntryRow items, each tappable to navigate to its account.

Lifecycle actions in the app bar:

Action	Visible when	What it does
Reverse	type is not REVERSAL	Posts an offsetting REVERSAL transaction.

A confirmation dialog precedes the mutation. Snackbar feedback on success / failure. The transaction's view is invalidated so the result surfaces immediately.

Permissions: transaction_view to read, transaction_manage to act.

/ledger/reports/trial-balance — Trial balance

Filter bar: currency, ledger type, ledger id.

The body has:

1. Per-currency totals card — one row per currency, with a green BALANCED or red UNBALANCED chip from the is_balanced flag. This is the textbook integrity check: total_debits == total_credits.
2. Per-account lines — DataTable of Account / Ledger / Type / Currency / Debits / Credits / Net.

Export in the app bar: CSV / Excel / PDF.

Reachable from:

• The main nav ("Trial balance").
• Pre-scoped to one ledger via ?ledgerId=….

Permissions: report_view.

Permissions reference

Permission	Grants
ledger_view	Read chart-of-accounts
ledger_create	Create / update ledgers
account_view	Read accounts and balances
account_create	Create / update accounts
transaction_view	Read transactions and entries
transaction_create	Create transactions and trigger Reverse
report_view	Run trial balance and account statement reports + exports

Providers

Provider	Returns
ledgerSearchProvider(query)	List<Ledger>
accountSearchProvider(query)	List<Account>
transactionSearchProvider(query)	List<Transaction>
transactionEntrySearchProvider(query)	List<TransactionEntry>
trialBalanceProvider(query)	TrialBalanceReport (derived client-side)
accountStatementProvider(query)	AccountStatementReport (derived client-side)
transactionNotifierProvider	mutations: create / reverse / update
ledgerNotifierProvider	mutations: create / update
accountNotifierProvider	mutations: create / update

Each Notifier exposes an AsyncValue<void> for loading / error state plus a method that returns the resulting domain object on success.

Exporting reports — what the user sees

1. Open a report screen (trial balance or account statement).
2. Apply filters; the screen re-fetches.
3. Tap the download icon in the app bar.
4. Pick the format: CSV / Excel / PDF.

What happens by platform:

• Web: the file downloads via an anchor.
• iOS / Android: the system share sheet opens — save to Files, AirDrop, send via WhatsApp, etc.
• Desktop: a Save-As dialog opens.

PDFs always route through the OS print preview (so AirPrint / Generic PDF Printer / Save as PDF are all available).

Embedding into a host app

import 'package:antinvestor_ui_ledger/antinvestor_ui_ledger.dart';
import 'package:antinvestor_ui_core/routing/route_module.dart';

final modules = <RouteModule>[
  LedgerRouteModule(),
  // …other modules
];

// Build the GoRouter with all module routes.
final router = GoRouter(
  routes: modules.expand((m) => m.buildRoutes()).toList(),
);

// Build the nav drawer / rail with all module nav items.
final navItems = modules.expand((m) => m.buildNavItems()).toList();

// Aggregate permissions across modules for role-driven UI.
final manifests = modules.map((m) => m.permissionManifest).toList();

Local development

cd ui/ledger
flutter pub get
flutter analyze

All dependencies resolve from pub.dev (antinvestor_api_ledger ^1.53.0, antinvestor_api_common ^1.53.1, antinvestor_ui_core ^0.5.0). To regenerate the Dart SDK after editing proto/ledger/v1/ledger.proto:

make proto-generate-dart

To publish the proto and the Go gen:

make proto-push

Then bump the Go module:

GOPROXY=direct go get \
  buf.build/gen/go/antinvestor/ledger/protocolbuffers/go@latest \
  buf.build/gen/go/antinvestor/ledger/connectrpc/go@latest
