Twenty-four of them, published and maintained under comapps.be. Fourteen run right here, in the browser, compiled from the packages that are published on pub.dev.
Widgets and plugins, each with an example you can open.
Flutter parallax widgets
Parallax widgets in pure Dart, with no dependencies. A container mode and a per-item mode, either axis, and a drift, a zoom, a blur and an overlay that are each configured on their own. The demo is the package’s own example: thirteen screens behind a menu.
Flutter scroll reveal widgets
Scroll reveal widgets in pure Dart, with no dependencies. Blocks fade, slide, zoom, blur, turn, flip or open into place as they come into view, or with the scroll, and the pieces inside them can follow one after the other. The demo is the package’s own example: a travel page and eleven screens behind a menu.
Flutter barcode and QR code scanner
Barcode and QR code scanner from one call, on Android, iOS, Linux, macOS, web and Windows.
Identity cards read from Dart and Flutter: a core that knows card commands, one package per kind of document, and one per way of reaching the card.
Read the Belgian eID card in Dart and Flutter
Reads the Belgian eID, the Kids ID and the residence cards through their contact chip: identity, address, photo and certificates, with no PIN. Checks the National Register’s signatures and has the chip prove it is genuine. The demo runs on a simulated card.
Read passports and identity cards in Dart and Flutter
Reads the contactless chip of passports worldwide and of the European identity cards issued since 2021, in pure Dart over any eid transport. Opens it with BAC or PACE from the MRZ or the CAN, reads the identity, the face and the other data groups, and checks the issuing state’s signature and that the chip is not a copy. The demo is the eid_nfc example, on simulated documents.
Dart electronic identity cards, the common ground
The common ground of electronic identity cards, in pure Dart: card commands, file reading, card insertion and the values national cards share. Document packages such as eid_belgium and eid_icao read the cards themselves.
Flutter USB and PC/SC card reader transport
Reads electronic identity cards through a USB or PC/SC card reader in Flutter: the eid transport for the ccid plugin, every reader at once, those plugged in later included.
Flutter NFC transport for phones
Reads electronic identity documents through the NFC of an Android phone or an iPhone: the eid transport for the flutter_nfc_kit plugin. With eid_icao, it reads passports and identity cards.
One job each, no ecosystem to buy into, and nothing about them is tied to the products they came out of.
Dart VAT number validation
A VIES client: validates European VAT numbers and reads back what the register holds. The demo takes a number apart in the browser; the lookup itself needs a server.
Dart HTML, CSS and JavaScript minifier
HTML, CSS and JavaScript minifiers in pure Dart. One call minifies a whole page.
EN 16931 as Dart objects, the two syntaxes that carry it, and one package per national or sector profile, so you depend only on the rules you are claiming.
Dart e-invoicing, Factur-X
The Factur-X profile: its five levels and what each one asks for.
Dart e-invoicing, XRechnung
The XRechnung profile, and the rules Germany adds on top of the norm.
Dart e-invoicing, UBL.BE
The UBL.BE profile, and the rules Belgium adds on top of the norm.
Dart e-invoicing, the EN 16931 semantic model
The norm as Dart objects. Builds and checks the semantic model, syntax aside.
Dart e-invoicing, UBL 2.1 syntax
Reads and writes the invoice as UBL 2.1, the syntax Peppol and most of Europe use.
Dart e-invoicing, UN/CEFACT CII syntax
Reads and writes the invoice as UN/CEFACT CII, the syntax France and Germany use.
Dart e-invoicing, Peppol BIS Billing 3.0
The Peppol BIS Billing 3.0 profile: its identifiers and the rules it adds.
A server-side GraphQL stack for Dart, from the lexer to the code generators, each layer usable on its own.
Dart GraphQL server
A GraphQL server runtime: queries, mutations and subscriptions against a schema.
Dart GraphQL type system
The GraphQL type system in Dart: objects, unions, enums, inputs and scalars.
Dart GraphQL parser
Parses queries and schemas into an AST whose every node carries a source span.
Dart GraphQL code generation
Generates graphql_schema3 types from annotated Dart classes at build time.
Dart GraphQL SDL generation
Generates an SDL schema from plain Dart classes. Reads the code, not a running server.
Dart GraphQL annotations
The annotations graphql_schema_generator reads: directives, interfaces and scalars.
Dart GraphQL to REST code generation
Generates a Dart server from a schema: models, resolver stubs, REST endpoints and docs.
Nothing matches . Everything is on pub.dev too.
