我在一些颤抖的依赖中看到这一点,并且一直想知道这意味着什么,因为我这些天经常看到它.
示例pubspec.yaml
dependencies:
flutter:
sdk: flutter
cloud_firestore: ^0.8.1+1
sqflite: 0.12.2+1
zoomable_image: ^1.2.1+1
我检查了here但没找到它.
什么意思？它也可以是2吗？
意味着它是一个常规版本,
而 – 表示预发布版本.
(x.y.z之后没有内部版本号也表示发布版本如此)
该版本的以下部分是一些没有固定格式的内部版本号.
也可以看看

从https://semver.org/spec/v2.0.0-rc.1.html开始
-
A pre-release version MAY be denoted by appending a dash and a series of dot separated identifiers immediately following the patch version. Identifiers MUST be comprised of only ASCII alphanumerics and dash [0-9A-Za-z-]. Pre-release versions satisfy but have a lower precedence than the associated normal version. Examples: 1.0.0-alpha,1.0.0-alpha.1,1.0.0-0.3.7,1.0.0-x.7.z.92.
-
A build version MAY be denoted by appending a plus sign and a series of dot separated identifiers immediately following the patch version or pre-release version. Identifiers MUST be comprised of only ASCII alphanumerics and dash [0-9A-Za-z-]. Build versions satisfy and have a higher precedence than the associated normal version. Examples: 1.0.0+build.1,1.3.7+build.11.e0f985a.
提示：除非 – 明确是pubspec.yaml中版本约束的一部分,否则flutter包get会忽略预发布版本(带 – )
foo_package: ^1.2.3-beta
