I find solution. Delete those file from folder
".idea" file
"build" file
"pubspec-lock" file.
After delete "flutter clean" form terminal. Then "pub get".
Solution 3:[3]
- flutter clean
- flutter pub get

Solution 4:[4]
You should search which dependency broke your build :
flutter pub deps
Find globally win32 in the result, and take the faulty dependency.
For me, it was path_provider:
|-- path_provider 1.6.18 <- Latest version 2.0.1
| |-- flutter...
| |-- path_provider_linux 0.0.1+2
| | |-- flutter...
| | |-- path...
| | |-- path_provider_platform_interface...
| | '-- xdg_directories 0.1.2
| | |-- meta...
| | |-- path...
| | '-- process 4.1.0
| | |-- file...
| | |-- path...
| | '-- platform...
| |-- path_provider_macos 0.0.4+4
| | '-- flutter...
| |-- path_provider_platform_interface 1.0.3
| | |-- flutter...
| | |-- meta...
| | |-- platform 3.0.0
| | '-- plugin_platform_interface...
| '-- path_provider_windows 0.0.4+1
| |-- ffi 0.1.3
| |-- flutter...
| |-- meta...
| |-- path...
| |-- path_provider_platform_interface...
| '-- win32 1.7.3 <--- Here
| '-- ffi...
Go to https://pub.dev/ and take the latest version. Then, make futter clean && flutter pub get and try to rebuild your app.

Adding ffi: ^1.0.0 in my pubspec.yaml resolved for me.
Solution 7:[7]
Upgrading all the packages to the latest version fixed my issue. since it's been quite a while since I last opened this project.

You should search which dependency broke your build:
- first there is an android studio plugin "Flutter Enhancement suite" install it it will show you which dependency need to be update to newer version.
- Dependencies that are conflicting change them to any like cupertino_icons: ^1.0.2 auto_size_text: ^2.1.0 path_provider: any
- run pub get.
- go to pub pubspec.lock file
- search for dependencies version that you changed to any in step 2.
- replace versions in pubspec.yaml . and its done[enter image Flutter Enhancement suite][1]
