Le aziende Google e Canonical si sono espressi<\/a><\/noindex> con un'iniziativa congiunta per fornire supporto allo sviluppo di applicazioni grafiche basate sul framework Flutter<\/a><\/noindex> per sistemi Linux desktop. Il framework per la creazione dell'interfaccia utente Flutter \u00e8 scritto<\/a><\/noindex> \u00e8 basato sul linguaggio Dart (motore runtime per l'esecuzione di applicazioni \u00e8 scritto<\/a><\/noindex> in C++), consente di creare applicazioni universali che funzionano su diverse piattaforme ed \u00e8 considerato un'alternativa a React Native.<\/p>\n

Nonostante esista un Flutter SDK per Linux, fino ad ora era stato utilizzato solo per lo sviluppo di applicazioni mobili e non supportava la creazione di applicazioni desktop per Linux. Lo scorso anno, Google ha annunciato l'intenzione di aggiungere a Flutter la possibilit\u00e0 di sviluppare programmi desktop completi e ha presentato una versione alpha per la creazione di tali programmi per macOS. Ora Flutter \u00e8 stato ampliato<\/a><\/noindex> con la possibilit\u00e0 di sviluppare applicazioni desktop per Linux. Il supporto per lo sviluppo di applicazioni per Windows \u00e8 attualmente in fase di prototipo iniziale.<\/p>\n

Per il rendering dell'interfaccia su Linux viene utilizzato<\/a><\/noindex> c'\u00e8 un wrapper basato sulla libreria GTK (il supporto per Qt e altri toolkit \u00e8 previsto in futuro). Oltre al linguaggio nativo di Flutter Dart, utilizzato per creare i widget, le applicazioni possono usare l'interfaccia Dart Foreign Function per chiamare codice in C\/C++ e accedere a tutte le funzionalit\u00e0 della piattaforma Linux. <\/p>\n

Il supporto per lo sviluppo di applicazioni per Linux \u00e8 stato introdotto nella fresca versione alpha Flutter SDK<\/a><\/noindex>, nella quale \u00e8 stata anche implementata la possibilit\u00e0 di pubblicare applicazioni Linux nel catalogo Snap Store. In formato snap \u00e8 possibile trovare anche la versione stessa Flutter SDK<\/a><\/noindex>. Per sviluppare applicazioni basate su Flutter si consiglia di utilizzare l'editor di codice Visual Studio Code o gli ambienti di sviluppo IntelliJ e Android Studio. <\/p>\n

Come esempio di applicazioni Linux basate su Flutter \u00e8 stata proposta l'applicazione Flokk Contacts<\/a><\/noindex> per gestire la rubrica di Google Contacts. Nel catalogo pub.dev<\/a><\/noindex> sono stati pubblicati tre plugin Flutter con supporto per Linux: url_launcher<\/a><\/noindex> per aprire URL nel browser predefinito, shared_preferences<\/a><\/noindex> per salvare le impostazioni tra le sessioni e path_provider<\/a><\/noindex> per determinare le directory standard (download, immagini, video, ecc.)<\/p>\n
