前提：Flutter 項(xiàng)目中引入使用多個(gè)插件，內(nèi)含有swift與靜態(tài)庫時(shí)出現(xiàn)的一系列問題

問題一鬓催、swift插件缺少設(shè)置swift的版本號(hào)

解決方案：在Xcode中打開項(xiàng)目Targets—>builds settings —>user-defined
在user-defined內(nèi)添加一行：SWIFT_VERSION（版本號(hào)視當(dāng)前版本號(hào)為準(zhǔn)）

問題二、靜態(tài)庫
看到網(wǎng)上好多的解決方法是刪除掉或者添加上Podfile中的use_frameworks!,實(shí)測(cè)與此無關(guān),錯(cuò)誤信息忘記截圖啦??蹲嚣，大體就是pod install 時(shí)出現(xiàn)無法install之類的信息
正解方法是找到相關(guān)錯(cuò)誤插件內(nèi)的podspec文件徘意，添加s.static_framework = true
