Flutter安裝Dart版本SDK為1.24.3-不是Dart 2

Question

我已經安裝了Flutter incl。 飛鏢跟隨此

並確保我擁有最新的： flutter upgrade

但是dart --version Dart VM version: 1.24.3 (Wed Dec 13 23:26:59 2017) on "macos_x64"顯示了Dart VM version: 1.24.3 (Wed Dec 13 23:26:59 2017) on "macos_x64"

那不是2.x嗎？

flutter --version

輸出：

Flutter 0.4.4 • channel beta • https://github.com/flutter/flutter.git
Framework • revision f9bb4289e9 (3 weeks ago) • 2018-05-11 21:44:54 -0700
Engine • revision 06afdfe54e
Tools • Dart 2.0.0-dev.54.0.flutter-46ab040e58

注意：嗯，我將嘗試查找路徑更改...

where dart

輸出：

/usr/local/bin/dart
/usr/local/bin/dart

謝謝

Answer 1

Flutter在<flutter_dir>/bin/cache/dart-sdk/bin/dart下打包了自己的dart版本。 這就是為什么您看到兩個版本。

所以如果你跑

$ <flutter_dir>/bin/cache/dart-sdk/bin/dart --version

您可能會得到類似

Dart VM version: 2.0.0-dev.54.0.flutter-46ab040e58 (Fri May 11 17:50:46 2018 +0000) on "linux_x64"
