Seems there are bugs on android with position: absolute in <BlurView />. Related to this issue https://github.com/Kureev/react-native-blur/issues/483

I think this is not the case. Inside same view these two behaves differently

// Doesn't blur, only adds an alpha
<MapView
    mapType={'standard'}
    style={StyleSheet.absoluteFill}
    userInterfaceStyle={'dark'}
    initialRegion={{
        latitude: 20.646201934797862,
        latitudeDelta: 66.42422647230924,
        longitude: -85.31906712412702,
        longitudeDelta: 43.3273031470187,
    }}
/>
// Blur works as expected
<ImageBackground
  source={{uri: 'https://picsum.photos/640/360'}}
  style={StyleSheet.absoluteFill}
  resizeMode={'cover'}
/>

Having the same problem. Components outside MapView are getting blurred, but MapView itself not.

I solved it by creating a webView...

import * as React from 'react'
import { WebViewProps } from 'react-native-webview'

import { View, WebView } from './view'

function getHtmlStr(blur = 10) {
  return `<body style="margin: 0;">
        <div style="height: 100vh; width: 100vw; backdrop-filter: blur(${blur}px);"></div>
      </body>`
}

export const BlurWebview = ({
  className,
  blurAmount,
  children,
  ...props
}: WebViewProps & { blurAmount?: number }) => {
  return (
    <View className={className}>
      <WebView
        className="absolute h-full w-full bg-transparent"
        {...props}
        source={{ html: getHtmlStr(blurAmount) }}
      />
      {children}
    </View>
  )
}
