I am facing this issue when I run flutter pub run build_runner build. I have tried solutions like flutter clean, flutter pub-cache repair flutter pub get, etc. Dependencies like Mockito, HTTP, and build_runner are added on pubspec and flutter pub get ran successfully as well.

Failed to precompile build_runner:build_runner:

Try add these lines to your pubspec.yaml

dependency_overrides:
   meta: 1.6.0
user_69507680

dependency_overrides: analyzer: '1.5.0'

Adding this pubspec.yaml file worked for me

it seems to be an issue with newest verson of analyser. I was able to fix it by just downgrading the version from 1.6.0 to 1.5.0.

dev_dependencies: analyzer: 1.5.0

In my case build runner, I have upgraded build runner and few other dependency.

Build runner for generating part files

build_runner: ^2.1.2

Update dependencies to latest versions. It's works for me.

auto_route:
build_runner:
auto_route_generator:
user_91260170 
flutter pub upgrade --major-versions

This will do the thing. Happy coding.
