F\u00f6retagen Google och Canonical presenterat<\/a><\/noindex> med ett gemensamt initiativ f\u00f6r att st\u00f6dja utvecklingen av grafiska applikationer baserade p\u00e5 ramverket Flutter<\/a><\/noindex> f\u00f6r skrivbordssystem p\u00e5 Linux.

Trots att Flutter SDK f\u00f6r Linux finns, har det fortfarande anv\u00e4nts enbart f\u00f6r utveckling av mobilapplikationer och har inte st\u00f6tt byggandet av skrivbordsapplikationer f\u00f6r Linux. F\u00f6rra \u00e5ret meddelade Google sin avsikt att l\u00e4gga till m\u00f6jligheten att utveckla fullst\u00e4ndiga skrivbordsprogram i Flutter och presenterade en alfa-version f\u00f6r utveckling av s\u00e5dana program f\u00f6r macOS. Nu har Flutter erweiterats<\/a><\/noindex> med m\u00f6jligheten att utveckla skrivbordsapplikationer f\u00f6r Linux. St\u00f6det f\u00f6r utveckling av applikationer f\u00f6r Windows \u00e4r fortfarande p\u00e5 prototypstadiet.<\/p>\n

F\u00f6r rendering av gr\u00e4nssnitt i Linux funktionen unix_crypt, som tar emot det l\u00f6senord som anv\u00e4ndaren anger utan att utf\u00f6ra escape av specialtecken. I git-repositoriet<\/a><\/noindex> finns en anpassning baserad p\u00e5 GTK-biblioteket (st\u00f6d f\u00f6r Qt och andra toolkit v\u00e4ntas komma senare). F\u00f6rutom det ursprungliga spr\u00e5ket Dart, som anv\u00e4nds f\u00f6r att skapa widgets, kan applikationer anv\u00e4nda Dart Foreign Function-interface f\u00f6r att anropa kod i C\/C++ och f\u00e5 tillg\u00e5ng till alla funktioner i Linux-plattformen. <\/p>\n

St\u00f6det f\u00f6r utveckling av applikationer f\u00f6r Linux erbjuds i den senaste alfa-versionen av Flutter SDK<\/a><\/noindex>, d\u00e4r det ocks\u00e5 har implementerats en m\u00f6jlighet att publicera Linux-applikationer i Snap Store-katalogen. I snap-formatet kan man \u00e4ven hitta byggversionen av Flutter SDK<\/a><\/noindex>. F\u00f6r utveckling av applikationer baserade p\u00e5 Flutter rekommenderas att anv\u00e4nda kodredigeraren Visual Studio Code eller utvecklingsmilj\u00f6erna IntelliJ och Android Studio. <\/p>\n

Som exempel p\u00e5 Linux-program baserade p\u00e5 Flutter f\u00f6resl\u00e5s applikationen Flokk Contacts<\/a><\/noindex> f\u00f6r att arbeta med Google Contacts. I katalogen pub.dev<\/a><\/noindex> har tre Flutter-plugins med st\u00f6d f\u00f6r Linux publicerats: url_launcher<\/a><\/noindex> f\u00f6r att \u00f6ppna URL:er i webbl\u00e4saren som \u00e4r standard, shared_preferences<\/a><\/noindex> f\u00f6r att spara inst\u00e4llningar mellan sessioner och path_provider<\/a><\/noindex> f\u00f6r att best\u00e4mma typiska kataloger (nedladdningar, bilder, videor etc.)<\/p>\n
