InputText: How to update the value without resetting ?

[Corezcy]

Version/Branch of Dear ImGui:

Version: 1.81
Branch: master

Back-end/Renderer/Compiler/OS

Back-ends: imgui_impl_OpenGL3.cpp + imgui_impl_glfw.cpp _
Compiler: bazel VScode
Operating System: Ubuntu 18.04.5 LTS

My Issue/Question:
I have a ImGui::InputText("aaa", b). At first, the string b is empty .The problem is that I will update the b outside(such as a button, when I enter the button , b will be assigned) , but in the next loop, the b is reset (actually b is empty again). So how can I update the b outside without resetting ? ? ? Or in outside I can change the content in the inputtext(aaa)?
Thanks a lot !

It's not possible via public api yet.
See PR #2890 and #1506
I will try to merge #2890 soon.
