I am on it

Any update guys? Want to install it for eslint 9 with FlatConfig but get error
TypeError: Key "rules": Key "@stencil-community/strict-boolean-conditions": Could not find plugin "@stencil-community".
Would appreciate any solution

[Oleksandr-Poshtaruk-KSO]

Seems like made it work with:

//eslint.config.mjs
import stencilPlugin from '@stencil-community/eslint-plugin'; // 0.9.0
import globals from 'globals';
import reactPlugin from 'eslint-plugin-react';
import typescriptEslintParser from '@typescript-eslint/parser';
import tseslint from 'typescript-eslint';
...
export default [
....
...tseslint.configs.recommended,
  {
    files: ['**/*.{ts, tsx}'],
    languageOptions: {
      parser: typescriptEslintParser,
      parserOptions: {
        project: './tsconfig.json',
      },
      sourceType: 'module',
      globals: globals.browser
    },
    plugins: {
      '@stencil-community': stencilPlugin,
      react: reactPlugin,
    },
    rules: {
      ...stencilPlugin.configs.strict.rules,

      "@typescript-eslint/semi": 'off',
      "@typescript-eslint/brace-style": 'off',
      "@typescript-eslint/func-call-spacing": 'off',

    },
  },
]

And had to turn off these rules. I think they are missed in "@typescript-eslint/eslint-plugin": "8.18.2",
"@typescript-eslint/semi": 'off',
"@typescript-eslint/brace-style": 'off',
"@typescript-eslint/func-call-spacing": 'off',

Sorry @Oleksandr-Poshtaruk-KSO , it takes way longer than I expected. Good I've found a solution.
