Question: getting error on 'react-native start'?
SyntaxError: Invalid regular expression: /(.*\\__fixtures__\\.*|node_modules[\\\]react[\\\]dist[\\\].*|website\\node_modules\\.*|heapCapture\\bundle\.js|.*\\__tests__\\.*)$/: Unterminated character class 
    at new RegExp () 
    at blacklist (D:\demo\app-kindie\node_modules\metro-config\src\defaults\blacklist.js:34:10)
It appears in \node_modules\metro-config\src\defaults\blacklist.js, there is an invalid regular expression that needed changed. You have to change the first expression under sharedBlacklist from:
var sharedBlacklist = [ 
    /node_modules[/\\]react[/\\]dist[/\\].*/, 
    /website\/node_modules\/.*/, 
    /heapCapture\/bundle\.js/, 
    /.*\/__tests__\/.*/ 
];
To
var sharedBlacklist = [ 
    /node_modules[\/\\]react[\/\\]dist[\/\\].*/, 
    /website\/node_modules\/.*/, 
    /heapCapture\/bundle\.js/, 
    /.*\/__tests__\/.*/ 
];
 Then you MUST clean project (go to android folder):
cd android 
.\gradlew clean
go back working folder and build again:
cd .. 
react native run-android
