call method

ReactElement call(Map props, [ dynamic c1 = _notSpecified, dynamic c2 = _notSpecified, dynamic c3 = _notSpecified, dynamic c4 = _notSpecified, dynamic c5 = _notSpecified, dynamic c6 = _notSpecified, dynamic c7 = _notSpecified, dynamic c8 = _notSpecified, dynamic c9 = _notSpecified, dynamic c10 = _notSpecified, dynamic c11 = _notSpecified, dynamic c12 = _notSpecified, dynamic c13 = _notSpecified, dynamic c14 = _notSpecified, dynamic c15 = _notSpecified, dynamic c16 = _notSpecified, dynamic c17 = _notSpecified, dynamic c18 = _notSpecified, dynamic c19 = _notSpecified, dynamic c20 = _notSpecified, dynamic c21 = _notSpecified, dynamic c22 = _notSpecified, dynamic c23 = _notSpecified, dynamic c24 = _notSpecified, dynamic c25 = _notSpecified, dynamic c26 = _notSpecified, dynamic c27 = _notSpecified, dynamic c28 = _notSpecified, dynamic c29 = _notSpecified, dynamic c30 = _notSpecified, dynamic c31 = _notSpecified, dynamic c32 = _notSpecified, dynamic c33 = _notSpecified, dynamic c34 = _notSpecified, dynamic c35 = _notSpecified, dynamic c36 = _notSpecified, dynamic c37 = _notSpecified, dynamic c38 = _notSpecified, dynamic c39 = _notSpecified, dynamic c40 = _notSpecified, ])

Returns a new rendered component instance with the specified props and children (c1, c2, et. al.).

The additional children arguments (c2, c3, et. al.) are a workaround for github.com/dart-lang/sdk/issues/16030.
