Vue-router cannot set the value of meta using the push method

using the push method of vue-router, setting the value of meta does not work. The code is as follows:

   this.$router.push({ path : "/bookGuide/deptList",   name : "deptList",  meta : { isBack : false }}, )

looked at the document and couldn"t find the reason. Does anyone know why?

cannot modify this meta value. At most, it should be used statically, or dynamically or honestly put the page data or Vuex.


can be modified.

this.$route.meta.isBack = true;
