how can i add user defined variable in pubspec.yaml for flutter?

Question

Basically I required to assign version and my local dependencies URL as user defined variable and assign the same in the path or wherever I wish to

Example like below

   mydependancyPath : D:\mylocalDependancy

   commonUtils:
   path:  mydependancyPath

1.Please let me know how can I achieve as like above

2.Is it possible to import another YAML file into pubspec.yaml

In Android I can achieve as below

dagger_version=2.8

"com.google.dagger:dagger:${dagger_version}" 

Solution

Is it possible to import another YAML file into pubspec.yaml

• the answer to the above is No, it is not possible because pubspec.yaml does not support imports.

• Now for your main question : you can use YAML Anchors and Aliases for example :

  # this line has the path , and stored in varName for future use we use *varName
  mydependancyPath : &varNam D:\mylocalDependancy
  # this line has the version number , so we can use *vers as a key that holds the value 2.8
  myversion : &vers 2.8
  #!join is to concatinate 
  path : !join [*varName, *vers]
