I swear that I have completed these tasks before submitting:

• I have read the documentation here: https://meliorence.github.io/react-native-render-html/
• I have confirmed that this bug has not been reported yet

Decision table

• My issue does not look like “The HTML attribute 'xxx' is ignored” (unless
  we claim support for it),
• My issue does not look like “The HTML element <yyy> is not rendered”

Bug Report

When using react-native 0.64.x and react-native-render-html 6.0.2, npm install throws an error with unable to resolve dependency tree. When using npm install --legacy-peer-deps its working.
In the package.json delivered in the release, react-native 0.64.0 is already defined as devDependency. Therefore it should be easy to update the peerDependency.

Reproduction

1. create empty directory
2. create package.json with dependencies

"dependencies": {
"react-native":"^0.64.0",
"react-native-render-html": "^6.0.2"
}

3. run npm install

@Ainias Hey thank you for your report, good catch! That's probably due to how npm 7 works (I'm using 6.x locally); I'll fix that today.

@Ainias Thought I fixed in release 6.0.3. I added a CI step to avoid regressions, see https://github.com/meliorence/react-native-render-html/actions/runs/1046261556 but it failed again, investigation going on ...

@Ainias I think it's fixed in 6.0.4; could you try it out? CI still fails but it worked locally...

@Ainias Found out that it would fail with npm@7.7.6 but succeed with npm@7.20.0, because in the former, * in peerDependencies would be wrongly resolved to the latest instead of whichever; which would conflict with react-native → react requirement. That was an npm bug!
