BrazilLicensePlateDrawing

A set of Flutter Widgets which draw on the screen three different types of brazilian cars' license plates:

• Mercosul
• Three Letters (pattern from the 1990's)

Known Limitations

• These widgets were created to support only the expected number of characters, according to each plate type. Using more than the expected number of characters can lead to unexpected behaviours, like overflows and exceptions.
