flutter - 获取flutter中所有可用语言的列表

Question

我需要在DropdownButton中使用所有可用的语言(带有变体，例如“英语(英国)”)，但在flutter SDK或dart内置插件中找不到，所以我结束了this site的抓取，并创建了带有以下内容的lang_list.dart文件

const LANGLIST = ["Afrikaans","Afrikaans (South Africa)","Arabic","Arabic (U.A.E.)","Arabic (Bahrain)","Arabic (Algeria)","Arabic (Egypt)","Arabic (Iraq)","Arabic (Jordan)","Arabic (Kuwait)","Arabic (Lebanon)","Arabic (Libya)","Arabic (Morocco)","Arabic (Oman)","Arabic (Qatar)","Arabic (Saudi Arabia)","Arabic (Syria)","Arabic (Tunisia)","Arabic (Yemen)","Azeri (Latin)","Azeri (Latin) (Azerbaijan)","Azeri (Cyrillic) (Azerbaijan)","Belarusian","Belarusian (Belarus)","Bulgarian","Bulgarian (Bulgaria)","Bosnian (Bosnia and Herzegovina)","Catalan","Catalan (Spain)","Czech","Czech (Czech Republic)","Welsh","Welsh (United Kingdom)","Danish","Danish (Denmark)","German","German (Austria)","German (Switzerland)","German (Germany)","German (Liechtenstein)","German (Luxembourg)","Divehi","Divehi (Maldives)","Greek","Greek (Greece)","English","English (Australia)","English (Belize)","English (Canada)","English (Caribbean)","English (United Kingdom)","English (Ireland)","English (Jamaica)","English (New Zealand)","English (Republic of the Philippines)","English (Trinidad and Tobago)","English (United States)","English (South Africa)","English (Zimbabwe)","Esperanto","Spanish","Spanish (Argentina)","Spanish (Bolivia)","Spanish (Chile)","Spanish (Colombia)","Spanish (Costa Rica)","Spanish (Dominican Republic)","Spanish (Ecuador)","Spanish (Castilian)","Spanish (Spain)","Spanish (Guatemala)","Spanish (Honduras)","Spanish (Mexico)","Spanish (Nicaragua)","Spanish (Panama)","Spanish (Peru)","Spanish (Puerto Rico)","Spanish (Paraguay)","Spanish (El Salvador)","Spanish (Uruguay)","Spanish (Venezuela)","Estonian","Estonian (Estonia)","Basque","Basque (Spain)","Farsi","Farsi (Iran)","Finnish","Finnish (Finland)","Faroese","Faroese (Faroe Islands)","French","French (Belgium)","French (Canada)","French (Switzerland)","French (France)","French (Luxembourg)","French (Principality of Monaco)","Galician","Galician (Spain)","Gujarati","Gujarati (India)","Hebrew","Hebrew (Israel)","Hindi","Hindi (India)","Croatian","Croatian (Bosnia and Herzegovina)","Croatian (Croatia)","Hungarian","Hungarian (Hungary)","Armenian","Armenian (Armenia)","Indonesian","Indonesian (Indonesia)","Icelandic","Icelandic (Iceland)","Italian","Italian (Switzerland)","Italian (Italy)","Japanese","Japanese (Japan)","Georgian","Georgian (Georgia)","Kazakh","Kazakh (Kazakhstan)","Kannada","Kannada (India)","Korean","Korean (Korea)","Konkani","Konkani (India)","Kyrgyz","Kyrgyz (Kyrgyzstan)","Lithuanian","Lithuanian (Lithuania)","Latvian","Latvian (Latvia)","Maori","Maori (New Zealand)","FYRO Macedonian","FYRO Macedonian (Former Yugoslav Republic of Macedonia)","Mongolian","Mongolian (Mongolia)","Marathi","Marathi (India)","Malay","Malay (Brunei Darussalam)","Malay (Malaysia)","Maltese","Maltese (Malta)","Norwegian (Bokm?l)","Norwegian (Bokm?l) (Norway)","Dutch","Dutch (Belgium)","Dutch (Netherlands)","Norwegian (Nynorsk) (Norway)","Northern Sotho","Northern Sotho (South Africa)","Punjabi","Punjabi (India)","Polish","Polish (Poland)","Pashto","Pashto (Afghanistan)","Portuguese","Portuguese (Brazil)","Portuguese (Portugal)","Quechua","Quechua (Bolivia)","Quechua (Ecuador)","Quechua (Peru)","Romanian","Romanian (Romania)","Russian","Russian (Russia)","Sanskrit","Sanskrit (India)","Sami (Northern)","Sami (Northern) (Finland)","Sami (Skolt) (Finland)","Sami (Inari) (Finland)","Sami (Northern) (Norway)","Sami (Lule) (Norway)","Sami (Southern) (Norway)","Sami (Northern) (Sweden)","Sami (Lule) (Sweden)","Sami (Southern) (Sweden)","Slovak","Slovak (Slovakia)","Slovenian","Slovenian (Slovenia)","Albanian","Albanian (Albania)","Serbian (Latin) (Bosnia and Herzegovina)","Serbian (Cyrillic) (Bosnia and Herzegovina)","Serbian (Latin) (Serbia and Montenegro)","Serbian (Cyrillic) (Serbia and Montenegro)","Swedish","Swedish (Finland)","Swedish (Sweden)","Swahili","Swahili (Kenya)","Syriac","Syriac (Syria)","Tamil","Tamil (India)","Telugu","Telugu (India)","Thai","Thai (Thailand)","Tagalog","Tagalog (Philippines)","Tswana","Tswana (South Africa)","Turkish","Turkish (Turkey)","Tatar","Tatar (Russia)","Tsonga","Ukrainian","Ukrainian (Ukraine)","Urdu","Urdu (Islamic Republic of Pakistan)","Uzbek (Latin)","Uzbek (Latin) (Uzbekistan)","Uzbek (Cyrillic) (Uzbekistan)","Vietnamese","Vietnamese (Viet Nam)","Xhosa","Xhosa (South Africa)","Chinese","Chinese (S)","Chinese (Hong Kong)","Chinese (Macau)","Chinese (Singapore)","Chinese (T)","Zulu","Zulu (South Africa)"];

这样我就可以导入其他文件并使用此列表。
可以执行吗？ flutter 有没有做同样的事情的方法？
