Flutter - Dart : wait a forEach ends

Question

I try to modify a string using data in each node I retrieve from Firebase database, and then to write a file with the modifed string (called \"content\").

Answer 1

Have you tried:

File file = await cacheManager.getFile(signedurl);
content = content.replaceAll('test', file.path);

instead of:

cacheManager.getFile(signedurl).then((file){ ...});

EDIT:

Here's a fuller example trying to replicate what you have. I use a for loop instead of the forEach() method:

void main () async {
  List str = await getFuture();
  print(str);
  var foo;

  for (var s in str) {
    var b = await Future(() => s);
    foo = b;
  }

  print('finish $foo');
}

getFuture() => Future(() => ['1', '2']);
