Methods

addFileAssocation(String dcliPath) → void
Called during the install so that an OS that needs to create a file association between .dart and dcli can create that association. The implementor is responsible for not adding the association if it already exists.
override
addToPATH(String path) bool
Adds a path to the start script returns true if adding the path was successful
override
appendToPATH(String path) bool
Appends path to the end of the PATH in a persistent manner. Note: this doesn't update current scripts path. Returns true if we successfully appended the path. In almost all shells you will need to restart the terminal in order for the path change to take affect.
override
checkInstallPreconditions() String?
at this point no posix system has any preconditions.
inherited
install({bool installDart = false, bool activate = true}) Future<bool>
Install dart/dcli
inherited
installTabCompletion({bool quiet = false}) → void
If the shell supports tab completion then install it. If quiet is true then suppress any console output except for errors.
override
matchByName(String name) bool
Returns true if the shells name matches the passed name. The comparison is case insensitive.
inherited
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
prependToPATH(String path) bool
Prepends path to the start of the PATH in a persistent manner. Note: this doesn't update current scripts path. Returns true if we successfully prepended the path. In almost all shells you will need to restart the terminal in order for the path change to take affect.
override
privilegesRequiredMessage(String app) String
The message used during installation if it needs to be run with sudo.
inherited
releasePrivileges() → void
revert uid and gid to original user's id's You should note that your PATH will still be the SUDO PATH not your original user's PATH.
inherited
restorePrivileges() → void
If a prior call to releasePrivileges has been made then this command will restore those privileges If releasePrivileges hasn't been called then this method does nothing.
inherited
toString() String
A string representation of this object.
inherited
withPrivileges(RunPrivileged action, {bool allowUnprivileged = false}) → void
Run action with root UID and gid
inherited
